Question

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

C: as the temperature increases the speed of gas molecules increases

Answer 2

The correct option is C.

According to the kinetic theory of gases, the temperature apply to a gas affect the speed of motion of the gas particles. The higher the temperature of the gas, the faster the motion of the gas particles; the reverse is also true. This is because, as the temperature of the gas increases, the gas particles gain more kinetic energy and thus move faster and collide more with one another and with the walls of the container.
