Quick check
Answer each question before opening the answer.
Explain gas pressure using the particle model.
Gas particles collide with the container walls; the force of these collisions per unit area is the pressure.
Why does gas pressure increase with temperature at constant volume?
The particles move faster and hit the walls harder and more often.
