Solution

The average kinetic energy of a gas depends on the following factors:

  1. Temperature: The average kinetic energy of gas molecules is directly proportional to the temperature of the gas. As the temperature increases, the molecules move faster and their kinetic energy increases.

  2. Mass of the gas molecules: The average kinetic energy is inversely proportional to the mass of the gas molecules. Lighter gas molecules have higher average kinetic energy compared to heavier gas molecules at the same temperature.

  3. Velocity of the gas molecules: The average kinetic energy is directly proportional to the square of the velocity of the gas molecules. Faster-moving molecules have higher average kinetic energy.

In summary, the average kinetic energy of a gas depends on the temperature, mass of the gas molecules, and velocity of the gas molecules.
