in this module we will learn about another course of the Second World War and that is the policy of appeasement these students the word appease literally means to pacify or two please it was this time when the world economies were groaning under the destruction of the First World War and countries like Britain and France are leaders of league of nations were busy solving their own economic problems hence they did not want the second world war at any cost from may 1937 to September 1939 when the world war two broke out the policy of appeasement was given shape by British premier or Prime Minister Neville Chamberlain this policy means exceeding too hostile demands in order to gain peace policy of conciliating with an aggressive power at the cost of some other country is what appeasement means acceptance to undo threatening demands of germany in order to avoid war is what England and France were doing rather than taking a strict action against the German dictator adolf hitler they allowed Hitler to grow that is why Hitler openly flouted the clauses of treaty of vestals there are two main reasons as to why Britain and France follow the policy of appeasement towards Hitler first they believed that the treaty of Versailles had been to Syria for the defeated powers especially Germany second they thought that if genuine grievances of Germany were removed she would be satisfied and would do nothing to disturb the peace of the World they also felt that the strength of Hitler and Mussolini late in their ability to exploit the National grievances in their respective countries once these grievances are removed the two dictators would lose their appeal and the power could be reduced therefore they agreed to transfer the Sudetenland to Germany at the Munich conference which was held in 1938 they also did nothing when Germany began to rearm in complete violation of the terms of treaty of Versailles Britain and France were mistaken in their assessments when they give reasonable concessions to germany in actuality Hitler was taking an advantage of the modesty that for shown towards him Hitler’s demands grew shockingly excessive aiming at European mastery if not world conquest the policy of appeasement greatly emboldened Germany Italy and Japan who plunged the world into another destructive war England and France followed this policy but yet another intention they followed this policy towards dictators to create a bulwark against Soviet Union and check the rising tide of communism this is to be understood that Hitler was a staunch anti-communist whereas joseph Stalin was a hardline communist leader of Soviet Russia England and France had anticipated that if these two dictators fight against each other they would be mutually destroyed and hence in order to stop communism in this world they felt that they should empower Adolf Hitler Britain France the leaders of league of nations had a pastel dictators like Germany Italy and Japan in order to prevent the growth of communist USSR in Europe and communist china in Asia they had allowed the dictators to rearm because these dictators had signed and Auntie commented packed called as the Berlin room Tokyo axis . Dear student it is this Berlin Rome Tokyo axis which led to a second world war and hence the anticipation of Britain and France were proved wrong.

In this part we should learn some important symbols starting with roads, tanks, temple, huts ,river beds tree, well and forest if you take roads they’re shown in red color lines tanks again Rajasthan has plenty of dry tanks temple huts riverbed, trees well forest coming to different type of roads first one metaled road. metaled Road are also called pakka road this is metal road with a kilo meter stone backtracks these are utilized by donkeys mules they carry loads that’s why they’re called back track car track foot path foot path is shown with the dotted lines bridge again road with the bridge there’s a symbol of this is bridge with a piers as we can see here this is an extract of the certain way of india map that is sheet number 45/d well there are different type of roads. whenever there is a double line red color line it’s a metaled road. single red color lines are all cart tracks well they are motor able in dry season. now what do we understand by this it means that they cannot be crossed by cars or motors during for Rainey season as a ground becomes wet and muddy during cars or motors during for any season as a ground becomes wet and muddy doing rainy season but in the dry season when the ground is hard and dry motor can cross the area. what line is this backtrack. backtrack is shown in red color line but it is big dashes well here we take up two villages siori and pamera what type of road connects village siori and pamera well the answer will be cart track the reason is it is a single line and red color line if i take these two village siori and gulab ganj it would be a metaled road the reason is it’s a double line what type of road connects village singarli and harmatiya the answer would be pack track again because it is a single line and it is dashes know what type of road is this .this is single line but it is not dashes it is dotted well this is a foot path now we will see some more symbols like dry tank a topo map have plenty of dry tank let’s see they’re all we can see dry tank in this map oh we have plenty of dry tanks now these are called dry tanks because water can be seen only during rainy season the rest of the time in the year the tanks a dry tank with an embankment whenever there are lines at the bottom of the tank it will be called a dry tank with an embankment now what is an embankment and embankment is a race bank or a wall that is build to hold back water then a topo map and how plenty of temples especially near villages there will always be plenty of trees in a topo map and they are of two types one ordinary trees which are shown in green color and the other one survey trees which is shown in black color and is accompanied by a certain survey number as here you can see the number 285 well there are two types of well one is lined another one is unlined a line well is a pakka well there will be masonry work in it whereas unlined well is just stuck I mostly in the topo map most of the places you will see lined well unlined well is very rare it’s very less then huts when it comes to huts there are two types permanent huts and temporary huts. And mostly even see a permanent huts but of course in some places you will also see temporary huts coming to a river bed now what you’re seeing here is a riverbed this is a dry river bed the reason is it is Rajasthan where the amount of rainfall is very less and rainfall is seasonal so throughout the year it is dry except their rainy season now there are letters written like 6R what does it mean it refers to a relative depth now relative depth represents the approximate depth in meters between the top and bottom of a slope this is useful in understanding the river or the stream in which direction it flows so based on the flow of the river we can say that the river is moving from west towards east the reason is on one hand we see 5R there is on the other side we see 10R . our so here the depths less there is here the depth is more so we can say water is moving in this direction towards the reservoir. let’s take one more example but before that here we have left bank and the right bank so once we understand the flow of the river we also understand the left bank and the right bank now under the example that is starting from 3R to 6R here the flow will be in this direction so the left bank and the right bank will also change with this we conclude this module children..

Hello students today we will be doing the sixth chapter of commercial studies which is sales and selling process in this module will be doing the introduction to this chapter understanding the concept of sales and also learning the distinction between marketing and selling.selling is the heart of marketing it is a very important function of marketing it is because of this function that the firm continues to exist . let us now understand the concept of sales selling is largely and art as the effectiveness of selling depends on the competence and behavior of the salesperson if this is person is competent enough in convincing the customer by telling the features of the product like here the sales person is telling the features of the mobile phone to the consumer that the mobile phone has 2.7 gigahertz processor 2gb RAM 32gb storage and it is only worth rupes7,000 then he will succeed in selling the product and transferring the ownership of the product to the consumer selling is a process of finding customers and transferring goods to them for value. selling direct the flow of goods and services from the producers to the consumers. it involves the following activities first identifying all locating buyer, second finding out their needs and preferences third inducing them to buy forth negotiating terms of sale and fifth transferring ownershipand possession of goods for money. selling is a product oriented concept let us understand why the main focus of selling is the product to be sold it begins after production and ends when the ownership is transferred to the buyer of the product for a value let us now understand the distinction between marketing and selling. the first basis of distinction is meaning marketing means identifying and satisfying wants of the customers whereas selling means exchanging goods for money second basis is objective the main objective of marketing is ensuring growth and stability of the firms which is the long-term goals whereas the main objective of selling is maximizing profits by increasing the sales volume which is their short-term goals the third basis is orientation marketing is custom oriented which means you’re the seller has to be where they’re as selling is production-oriented which the seller has to be where.where as selling is production-oriented which means you’re the buyer has to where. the fourth basis is scope marketing is wider in scope as it includes selling where as selling is a narrow concept as it is a part of marketing beginning and end which is the fifth basis marketing begins before production and continues even after sales where as selling begins after production and ends with the sale of the product the sixth basis is focus the focus of marketing is external on the customers needs the focus of selling is internal on the seller’s needs the seventh basis demand marketing involves creation and maintenance of demand on where as selling presupposes the existence of demand in the market.the eight basis growth marketing is new and modern concept we’re selling is old and traditional concept the ninth bases this approachmarketing has an integrated approach for achieving long-term goals of the firm where as selling has fragmented approach which means it focuses on immediate gains the tenth basis is process marketing is a process of converting customer needs into products and services where selling is a process of converting products and services into cash. the eleventh and the final basis of distinction its nature of activity marketing involves philosophy and attitude we’re selling is routine and tactical

Hello students in this module we are going to study the large scale manufacture of sulphuric acid using contact process as we can see on the screen is the setup for the plant of manufacturing of sulphuric acid which is used in the industries let’s study each and every part of the plant in detail first on the left hand side we have the blower we’re air is pumped inside the plant we also have the iron pyrite or sulphur burners where cipher or iron pyrites undergo the oxydation in the presence of air to form sulphur dioxide next the entire setup as we are going to see is for cleaning the sulphur dioxide so form sulphur dioxide is first put into the dusting tower where all the dust particles are settle down further it is sent through cooling pipes were sulphur dioxide is cooled after which it is taken to the scrubbing tower for further removal of dust particles and then to the dry tower to remove any amount of moisture which is present and finally to the arsenic purifier where arsenic oxide impurities are removed now where are all the impurities are removed or not can be tested using the small testing box clean and dry sulphur dioxide which is from its next sent to the contact tower now this student is the most important process of the entire plant where sulphur dioxide is getting converted to sulphur trioxide after the sulphur trioxide conversion it is taken into the absorption tower where it’s absorbed by concentrated sulphuric acid after absorption by sulphuric acid it is then finally diluted in the delusion tank for the concentration which is required this is the entire setup of the plant now let us begin with the main process that is the contact process now the main reaction which is happening over is the clean and dry gas mixture of sulphur dioxide and oxygen which is then passed through the contact tower that is so2 is reacting with o2 to form so3 now this reaction is not very feasible and hence we require a catalyst to increase the speed of the reaction the catalyst which is added is vanadium pentoxide again we can also use platinized asbestos as a catalyst but it is not prefer the reason is because when vanadium pentoxide is cheaper and it is less easy poisoned by impurities so even after all that purification and some amount of abilities are present they might poisonize platinized asbestos catalyst which is rare in case of vanadium pentoxide the promoter which is used over here now what is exactly a promoter the promoter is a substance which is added to a solid catalyst to improve its performance in a chemical reaction here the catalyst is increasing the speed of the reaction the promoter would further increase the speed of the reaction he promoter which is used here is potassium oxide along with vanadium pentoxide now this is the reaction which is happening between sulfur dioxide and oxygen let’s first study the first step where we are forming sulphur dioxide it is done in the first part of the first chamber of the entire process which is the blower and cipher or pyrite burner production of sulphur dioxide then in this chamber by bombing sulphur or iron pyrites now iron pyrites is FeS2 they burned in the presence of purified air now why do we use purified air because heat energy would be wasted in eating the unreacted nitrogen component of the raw air that is why we purify the air and then use it let’s see the first reaction which is occurring between sulfur and oxygen if you’re using cipher in this case so S+O2 gives us SO2 as we can see the reaction is self balance or alternatively we can use iron pyrites so let’s see the oxidation of iron pyrites which happens FeS2 which is iron pyrites reacts with oxygen to form fe2O3 + SO2 now this reaction is not balanced on the right hand side we can see oxygen odd to make it even will multiply fe2O3 by 2 now iron has become 4 on the right hand side whereas on the left hand side it is just one so on the left hand side will multiply FeS2 by 4 cipher on the left hand side thus become 8 and on the right hand side it is 1 so we’ll multiply SO2 on the right hand side by 8 total oxygen on the right hand side has become 22 now so left inside oxygen will be multiplied by 11 and hence we have the balanced chemical equation for fes2 + 11 or to giving to fe2O3 + 8SO2 and that’s our self or dioxide is produced which is going to get further purified
