What will happen to the volume of a gas under constant temperature if the pressure increases?

• Increase
• Decrease
• Nothing
• Explosion!

How are pressure and volume related?

• Directly
• Indirectly
• They aren't related

What law combines all 3 factors (pressure, temperature, and volume)

• Combined Gas Law
• Charle's Law
• Boyle's Law
• Avagadros Ideal Gas Law

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the

• air molecules hit the walls of the tire less frequently
• rubber in the tires reacts with oxygen in the atmosphere
• air molecules speed up and collide with the tire walls more often
• air molecules diffuse rapidly through the walls of the tire.
