From the following statements, concerning ideal gas at any given temperature T, select the correct one(s)
(1) The coefficient of volume expansion at constant
pressure is same for all ideal gases
(2) In a gaseous mixture, the average translational kinetic
energy of the molecules of each component is same
(3) The mean free path of molecules increases with the
decrease in pressure
(4) The average translational kinetic energy per molecule
of oxygen gas is 3KT (K being Boltzmann constant)

Options

B. The average translational kinetic energy per molecule of oxygen gas is 3kT, k being Boltzmann constant
C. The mean-free path of molecules increases with increases in the pressure
D. In a gaseous mixture, the average translational kinetic energy of the molecules of each component is different.
