Pick the correct statement (s) :

A

The rms translational speed for all ideal-gas molecules at the same temperature is not the same but it depends on the mass.

B

Each particle in a gas has average translational kinetic energy and the equation `(1)/(2)mv^(2)_(rms)=(3)/(2)kT` establishes the relationship between the average translational kinetic energy per particle and temperature of an ideal gas. It can be concluded that single particle has a temperature.

C

Temperature of an ideal gas is doubled from `100^(@)C` to `200^(@)C`. The average kinetic energy of each particle is also doubled.

D

It is possible for both the pressure and volume of a monoatomic ideal gas to change simultaneously without causing the internal energy of the gas to change.
