Question

The kinetic energy of a molecule of a gas is directly proportional to the absolute temperature of the gas.

• A. True
• B. False

Answer 1

The correct option is A True

The average kinetic energy of a gas particle is directly proportional to the temperature. An increase in temperature increases the speed in which the gas molecules move. All gases at a given temperature have the same average kinetic energy. Lighter gas molecules move faster than heavier molecules.
