let me put it in one single world chemistry is nothing but it’s the study of matter chemistry is the study of matter for example if I am a chemist and if you give me any matter what would I like to do with that matters the first thing i would like to study what is present in that matter means what are the composition of that matter ok this matter does it contain carbon or does it contain nitrogen does it contain oxygen so I being a chemist the first thing we’ll do is I’ll study the composition now after studying the composition then next thing what I would like to do being a chemist people i would like to study their structure ok carbon present a nitrogen present the oxygen present how are they bonded to each other if they bounded to each other then what is a structure so chemistry is nothing but it’s a study of composition is a study of structure and after studying the composition and the structure that third thing what I would like to study about that matter is i would like to study their properties and when I say properties any properties like a melting point boiling point density viscosity and all that stuff okay so chemistry is nothing but a study of composition in the study of structure is a study of properties and after studying all this three what are the last thing i would like to do is I would like to study their users ok Jo bhi matter hai malum pad gaya . now where can I use this matter can i use it in the pharmaceutical industry what can I use it in the metalogical  industry or should I used in cosmetics and all that stuff ok so what does chemistry, chemistry is nothing but it study of composition is a study of structure it is a study of properties and finally the uses of Matter ,matter is something matter is something which has mass and which occupies space that is what we define matter as okay people now the very simple question to you all these people the benches that you are sitting right now is that a matter you’re thinking Exactly if you go to see this bench does it contain any mass obviously doesn’t occupy any space very obvious so it is obviously a matter ok now so if you go to see cars planes trains buses are the matter the answers yes again pay attention AMI matter  AMI matter exactly do i wait Something yes I definitely weight 65 in kg well do i occupy the space i definitely occupy one square foot of this universe oh I am obviously a matter okay people and this matter can exist in the form of solid liquid and gas so please remember people it is very important to know what is the matter and it is even more important to know the radius physical states that matters existing in in fact that is what we will be doing in this chapter because the name of the  chapter that I’m teaching you itself is called last states of matter so when I see these three other fundamental states of matter means do I have any other states of matter the answers yes we have also had the four states of matter and that four states of matter is what we call it as plasma and I’m sure you might be Aware about this okay but do you know what the funny thing we also have the 5th states of matter and that 5th states of matter is what we call it as a bose-einstein condensate so tell your everyone is available ok so totally we have five states of matter the funny thing is we also have the 6^th state of matter.  that six states of matter is what we call it as fermionic condensate already be called fermionic condensate ok so totally we have six states of matter in fact this is one of the chapter i was teaching in one of the branches ok now when i was teaching this when I was giving them this information one smart girl from the group got up and she said so you’re talking about the six states of matter we already have the seven states of matter in fact she told me that the seven states of matter  Quark condensate ok and again I was teaching in one more branch and there one more guy got up and he said so seven sates of matter  is an old story he said there’s also eight states of matter and he called that eight states of matter has thought wave .i have to personally admitted that I haven’t read about the last two states are not very clearly so if i have to talk about that has so many states of matter but if you talk about the fundamental States of matter it’s only solid liquid and gas
