Amy measured the tire pressure of her truck that was parked outside after a cold night. The daytime temperature reached a nice 65 °F. Assume Amy's tires do not have any leaks. Explain the change in tire pressure.

• The air molecules heated inside the tire causing them to move faster exerting more pressure on the inside walls of the tires.

• The air molecules heated inside the tire causing them to move faster exerting less pressure on the inside walls of the tires.

• The air molecules heated inside the tire causing them to move slower exerting more pressure on the inside walls of the tires.

• The air molecules heated inside the tire causing them to move slower exerting less pressure on the inside walls of the tires.

How is the temperature of a gas related to the kinetic energy of its particles?

• As the temperature extends, the kinetic energy of the particles decreases.

• As the temperature increases, the kinetic energy of the particles increases.

• As the temperature decreases, the kinetic energy of the particles increases.

• As the temperature intensifies, the kinetic energy of the particles decreases.
