a) According to the kinetic theory of gases, the molecules of a gas are identical and in random motion. The collisions made by these molecules on the walls of the container exert pressure on the walls. Deduce an expression for the pressure of an ideal gas and also find at what temperature the r.m.s. speed of hydrogen is double its value at STP. b) For a gas r = 3/2 and R is the universal gas constant, find the values of CP and CV .
Kinetic theory of gases is based on the molecular picture of matter. a) Write any two postulates of kinetic theory of gases. b) Write short note on: i) Equipartition of energy. ii) Mean free path
According to the kinetic theory of gases, gas molecules are always in random motion. a) State the law of equipartition of energy. b) What do you mean by ‘mean free path’? Give an equation for the mean free path
