Ideal Gas Law Review

Why does airescape from a tire when the tire valve is opened?

• The pressure outside the tire is lower than the pressure inside the tire.

• The pressure outside the tire is greater than the pressure inside the tire.

• The temperature is higher outside the tire than inside the tire

• There are more particles of air outside the tire than inside the tire.

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

If the pressure exerted by a gas at 298 K in a volume of 0.044 L is 3.81 atm, how many moles of gas are present?

• P1/T1 = P2/T2

• PV = nRT

• V1/n1 = V2/n2

• P1V1 = P2V2

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

If a nitrogen gas occupies a volume of 500 ml at a pressure of 0.971atm. What volume will the gas occupy at a pressure of 1.50 atm?  

• P1V1 = P2V2

• PV = nRT

• P1/T1 = P2/T2

• V1/n1 = V2/n2

If a balloon is cooled what will happen to the volume?

• Volume will increase

• Volume will decrease

• Volume will not change
