Assertion : The root mean square and most probable speeds of the molecules in a gas are the same
Reason : The Maxwell distribution for the speed of molecules in a gas symmetrical
Assertion : The ratio of specific heat gas at constant pressure and specific heat at constant volume for a diatomic gas is more than that for a monatomic gas
Reason : The molecules of a monoatomic gas have more degree of freedom than those of a diatomic gas.
