Chemistry 2001 JAMB Past Questions - Question 12: Which of the following statements is correct about the average kinetic energy of the molecules of a gas?

Correct Answer

C

Explanation

The correct statement about the average kinetic energy of the molecules of a gas is:

"It increases with an increase in temperature."

The average kinetic energy of gas molecules is directly proportional to the temperature of the gas. As the temperature increases, the molecules gain more kinetic energy and move faster on average. The other options are not generally correct in describing the relationship between average kinetic energy and pressure, constant pressure, or volume for a gas.
