The volume of a balloon is \(2.85 \mathrm{~L}\) at \(1.00 \times 10^{5} \mathrm{~Pa}\). What pressure is required to compress the balloon to a volume of \(1.70 \mathrm{~L} ?\)

The use of CFCs as refrigerants and propellants in aerosol cans has been discontinued as a result of concerns about the ozone layer. If an aerosol can contained \(350 \mathrm{~mL}\) of CFC gas at a pressure of \(5.0 \times 10^{5} \mathrm{~Pa}\), what volume would this gas occupy at \(101,325 \mathrm{~Pa}\) ?

A balloon occupies a volume of \(1.25 \mathrm{~L}\) at sea level where the ambient pressure is 1 atm. What volume would the balloon occupy at an altitude of \(10,700 \mathrm{~m}\), where the air pressure is only \(220 \mathrm{mmHg}\) ?

What is Charles's law, and what variables must be kept constant for the law to hold?

Which assumptions of the kinetic-molecular theory explain the behavior of gases described by Charles's law? Explain your answer.

A hot-air balloon has a volume of \(0.96 \mathrm{~m}^{3}\) at \(291 \mathrm{~K}\). To what temperature (in \({ }^{\circ} \mathrm{C}\) ) must it be heated to raise its volume to \(1.20 \mathrm{~m}^{3}\), assuming the pressure remains constant?

What is Gay-Lussac's law, and what variables must be kept constant for the law to hold?

Which assumptions of the kinetic-molecular theory explain the behavior of gases described by Gay-Lussac's law? Explain your answer.

A glass laboratory flask is filled with gas at \(25^{\circ} \mathrm{C}\) and 0.95 atm pressure, sealed, and then heated to \(117{ }^{\circ} \mathrm{C}\). What is the pressure inside the flask?

An aerosol can has an internal pressure of 3.85 atm at \(25^{\circ} \mathrm{C}\). What temperature is required to raise the pressure to \(18.0 \mathrm{~atm} ?\)
