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
• 4.36 L
