Asked by Tesla
magine that you have a partially inflated tire. If you add approximately two pumps more air into it from your tire pump, what do you expect to change when you compare the starting and ending state of the tire? Check all of the boxes that apply:
volume
temperature
pressure
moles of air molecules

All four.
Brief reasoning:
- Moles of air: increase — you pumped more air into the tire.
- Pressure: increases — more moles in the same general space (and because you pumped against the tire pressure).
- Volume: increases a bit — the tire’s rubber stretches a little as internal pressure rises, so volume goes up slightly.
- Temperature: rises (at least briefly) — work is done on the gas during pumping so its temperature goes up; if you wait long enough it will cool toward ambient and the temperature difference may disappear.
