Ideal Gas Law Review

Why is a gas easier to compress than a liquid or a solid?

• Its volume increases more under pressure than an equal volume of liquid does.

• Its volume increases more under pressure than an equal volume of solid does.

• The space between gas particles is much less than the space between liquid or solid particles.

• The volume o f a gas's particles is small compared to the overall volume of the gas.

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?

• PV = nRT

• P1/T1 = P2/T2

• V1/n1 = V2/n2

• P1V1 = P2V2

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

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
