Question

A student measures the air pressure inside her bicycle tires before and after she goes on a long bicycle ride. What will she most likely observe?

Answer 1

She will see that the pressure went up, not down!

Explanation:

1. In a closed system, The volume inside the tire shouldn't change much (the losses will be small)

2. For a closed system, the Pressure inside a bicycle tire will increase with the increase of its Temperature

3. In a long bicycle ride, the constant friction of the tire to the ground will heat up the air inside the tire, thus increasing the pressure inside the tire
