What does the kinetic theory state about the relationship between the speed and temperature of gas molecules?

Question

A.
As the temperature increases, the speed of gas molecules remains constant.
B.
As the temperature increases, the speed of gas molecules decreases.
C.
As the temperature increases, the speed of gas molecules increases.
D.
As the speed of gas molecules increases, the temperature becomes constant.
E.
As the temperature decreases, the speed of gas molecules increases.

Answer 1

The correct answer is:

C. As the temperature increases, the speed of gas molecules increases.

According to the kinetic theory of gases, the temperature of a gas is directly related to the average kinetic energy of its molecules. As temperature rises, the kinetic energy increases, which leads to an increase in the speed of the gas molecules.
