Question

Which of the following statement is true

• 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 1cc of hydrogen and 1cc of oxygen both at N.T.P.; oxygen sample has a large number of molecules

Answer 1

Answer: (A)

Absolute zero degree temperature is not zero energy temperature

Answer 2

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