You have a gas that has a pressure of 2.0 atm and a volume of 10 L. What would be the new volume if the pressure was changed to 1.0 atm?

• 5 L

• 20 L

• It would stay at 10L

• 1 L

When the temperature is constant (K) inside a balloon, if you add pressure on it, the volume will .....

• Decrease

• Increase

• Not change at all

• the gas particles will solidify

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

Temperature describes  the ______________ of particles.
