Asked by Tesla
Jennifer checked the pressure in her bike tires before school and they had a pressure of 0.890 atm. She checked the tire pressure again after school and they had a pressure of 1.01 atm. Why was there an increase in pressure? Check all that apply.
The temperature increased outside.
The temperature decreased outside.
The air molecules in the tire moved around more rapidly later in the day and collided with the tire walls with more force.
There was a hole in the tire.

Select:
- The temperature increased outside. (Yes.)
- The air molecules in the tire moved around more rapidly later in the day and collided with the tire walls with more force. (Yes.)
Explanation: At roughly constant volume and number of moles, pressure rises when temperature rises (ideal gas law P ∝ T). Higher temperature means molecules have more kinetic energy, collide more often and with greater force, so pressure increases. A temperature decrease or a hole would produce a pressure drop, not an increase.
