    f= degrees of freedom ..
    which for monoatomic molecule/atom is 3 (x,y,z translational degrees of freedom)
    for diatomic under low temp f=5 two extra rotational df .. under high Temp it will have vibrational df too..

    Guys at 53.37 apply the formula K.E = FKT/2 for one molecule of gas where F stands for Degree of freedom....and for diatomic gas F must be 5 hence correct formula will be 5KT/2.....
    Hope you guys understand.......

    --> PV = 1/3mnV²
    --> for one mole
    RT= 1/3mnV²
    mn = total mass of gas = 4g
    --> RT = 1/3(4)(20)²
    Substituting R value we get

    At 31:35 the formula of force exerted is given but the derivation done must be wrong as F=dP/dt where dt is the time taken for the collisionor the contact time with the wall what was given there as time was the force between 2 sucssessive collisions(one after the other) in which acceleration occurs only at one point that is only at the instant of collision so
    dp/dt= mdv/dt or ma (F=ma) acceleration is happening only during the collision not throughout the movement of the molecule through the container.

    53:30 - Sir, you said that it is only valid in monatomic gas but O2 is a diatomic gas... So it was not happen but you do it by that method... So how was this possible...

    19:38 we know that gravity on an object doesn't depends upon mass. But here, sir said that gas molecules are so light that gravity has no effect on gas molecules.

      Acceleration due to gravity does not depend on mass....but force of gravitation depends upon both mass of the earth as well as mass of the body on which gravitational force acts
      F= (G m1 m2)/r^ 2
