What will happen to the volume of a balloon if you put it into hot water?

• Volume will increase

• Volume will decrease

• Volume will not change

Which of the following would increase the (gas) pressure of a system?

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

If the temperature of a gas decreases, the pressure...

• Decreases

• Increases

• Does not change

Which container will have lower pressure?

• left
• right
• they both have the same pressure

Gas laws involve what three variables?

• Solid Liquid Gas 
• Speed Velocity Acceleration 
• Elements Compounds Mixtures 
• Pressure Temperature Volume 

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.

The kinetic molecular theory of matter states that all of the particles that make up matter are constantly

• growing

• shrinking

• crying

• moving

At higher temperatures...

• particles in an object have less energy
• particles in an object move faster
• a gas contracts

If you place a balloon in a freezer what happens to the size of the balloon?

• Doubles
• increases
• decreases
• stays still
