This is our next concept : gases and kinetic theory
In our course book pg.no: 125 to 126.
This concept will  discuss about
1.??why does a gas exert pressure
2.?what happens to gas when it is heated
3.?What happens when gas is compressed

So in our course book pg no: 125 figure 9.10 and 9.11 support the concept clearly
Along with that watch the above video..
It says  what is brownian motion and how particle movement will be in gases..
