At a constant pressure, if the temperature is increased, what happens to the volume?

• Increases

• decreases

• stays the same

When the temperature of matter increases the particles...

• speed up and move closer
• speed up and move farther apart
• slow down and move closer together
• slow down and move farther apart

Which container will have lower pressure?

• left
• right
• they both have the same pressure

Which of the following would increase the pressure on a system?

• Increase the Temperature
• Pump in more gas
• Decrease the volume
• All of these

Directly proportional means that as one value increases ....................

• the other stays the same 
• the other increases as well
• the other decereases
• the other goes to zero

At constant temperature, the volume and pressure of a gas are ........

• inversely proportional

• directly proportional

• Volume will increase
• Volume will decrease
• Volume will not change

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.
