• decrease

When Volume increases then Pressure must...

• Increase

• Decrease

What type of relationship to pressure and volume have?

• direct

• inverse

• no relationship

• I don't know

Which container will have a lower pressure?

• left

• right

• they both have the same pressure

• I don't know

What causes pressure?

• The walls of the container

• The vacuum in the container

• The collisions of the particles

• Atmospheric pressure acting on the outside walls

A gas that has a pressure of 2 atm and a volume of 10 L.  What would be the new volume if the pressure was changed to 1 atm?

• P1/T1 = P2/T2

• P1V1 = P2V2

• V1/n1 = V2/n2

• PV = nRT

A sample of a gas has a volume of 852 mL at 298 K. What temperature is necessary for the gas to have a volume of 945 mL?

• Pt = P1 + P2 + P3 + ...

• P1V1 = P2V2

• V1/T1 = V2/T2

• P1V1/T1 = P2V2/T2

Determine the number of moles in a container of gas at STP with a volume of 99.2 L. 

• V1/n1 = V2/n2

• PV = nRT

• P1/T1 = P2/T2

• V1/T1 = V2/T2

Calculate the volume that a 0.323-mol sample of a gas will occupy at 265 K and a pressure of 0.900 atm.

• 7.18 L 

• 7.81 L

• 4.63 L
