Question

Two containers hold an ideal gas at the same temperature and pressure. Both
containers hold the same type of gas, but container B has twice the volume of container A. What is the average translational kinetic energy per molecule in container B? A. Twice that of container A
B. The same as that of container A C. Half that of container A
D. Impossible to determine

Answer 1

Average kinetic energy per molecule of a gas

E=3kT/2

k=Boltzmann's constant

T=temperature

Here temperature is same for both gases. Hence average kinetic energy is same.

Option B
