Which of the following statement is true?

Options

A. Absolute zero degree temperature is not zero energy temperature
B. Two different gases at the same temperature pressure have equal root mean square velocities
C. The rms speed of the molecules of different ideal gases. Maintained at the same temperature are the same.
D. Given sample of 1 cc of hydrogen and `1 cc` of oxygen both at N.T.P. Oxygen sample has a large number of molecules.

Answer

A

Explanation

At absolute temperature kinetic energy of gas molecules becomes zero but they posses potential energy so we can say that absolute zero degree temperature is not zero energy temperature.
