Question

6 a.m. - 30 psi
9 a.m. - 32 psi
1 p.m. - 35 psi
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.
a the air molecules heated inside the tire causing them to move faster exerting more pressure on the inside walls of the tires.
b the air molecules heated inside the tire causing them to move faster exerting less pressure on the inside walls of the tires.
c the air molecules heated inside the tire causing them to move slower exerting more pressure on the inside walls of the tires.
d the air molecules heated inside the tire causing them to move slower exerting less pressure on the inside walls of the tires.

Explanation:

According to the kinetic - molecular theory, when the temperature of a gas (air in the tire) increases, the kinetic energy of the gas molecules increases. Faster - moving molecules collide more frequently and with greater force against the walls of the container (tire), resulting in higher pressure.

Answer:

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