Critical Thinking! If gas particles in a tire are moving slowly, your tire pressure will drop because the gas particles are not pressing against the walls of the tire. What temperature change do you think would cause this pressure drop?
The temperature will have become colder
The temperature will have become hotter
Temperature and pressure have no relation
What can cause matter particles to speed up or slow down?
