Question

When the absolute temperature of a gas doubles, the average kinetic energy of the gas particles is

A. reduced by half.
B. doubled.
C. increased by half.
D. left unchanged.

Answer 1

The average kinetic energy is also doubled. B.

That is because there is a direct relationship between absolute temperature of gas and average kinetic energy of the gas.
If the absolute temperature of gas increases or decreases, the average kinetic energy would also increase or decrease accordingly.
