Would chlorine gas be suitable for weather balloons? Explain.

Aerosol Cans Use the kinetic theory to explain why pressurized cans carry the message "Do not incinerate."

Compare and contrast how a barometer and a tire-pressure gauge measure gas pressure.

A $120-\mathrm{mL}$ sample of nitrogen is collected at $900 \mathrm{~mm} \mathrm{Hg}$ and $0^{\circ} \mathrm{C}$. What volume will the nitrogen have when its temperature rises to $100^{\circ} \mathrm{C}$ and the pressure increases to $15 \mathrm{~atm}$ ?

A sample of argon gas is compressed into a volume of 0.712 L by a piston exerting a pressure of 3.92 atm of pressure. The piston is slowly released until the pressure of the gas is 1.50 atm. The new volume of the gas is

a) 0.272 L. b) 3.67 L. c) 1.86 L. d) 4.19 L.

A sample of carbon dioxide is collected at STP. Its volume is $500 \mathrm{~L}$. What volume will it have if the pressure is $380 \mathrm{~mm} \mathrm{Hg}$ and the temperature is $100^{\circ} \mathrm{C}$ ?

Analyzing If the volume of a helium-filled balloon increases by 20 percent at constant temperature, what will the percentage change in the pressure be?

If the valve in a tire pump with a volume of $0.78 \mathrm{~L}$ fails at a pressure of $9.00 \mathrm{~atm}$, what would be the volume of air in the cylinder just before the valve fails?

A 45-mL sample of ammonia gas at STP is heated to 73 degree C at constant pressure. What will the volume be?

The volume of gas at 101 kPa is 400 mL. If the pressure changes at constant temperature to 404 kPa, what will the new volume be?

Hospitals buy 400-L cylinders of oxygen gas compressed at $150 \mathrm{~atm}$. They administer oxygen to patients at $3.0 \mathrm{~atm}$ in a hyperbaric oxygen chamber. What volume of oxygen can a cylinder supply at this pressure?

In a chemical plant, xenon hexafluoride is stored at STP. Express these conditions using the Kelvin scale.

How many liters of hydrogen will be needed to react completely with 10 L of oxygen in the synthesis of hydrogen peroxide?

At one sewage-treatment plant, bacteria cultures produce $1000 \mathrm{~L}$ of methane gas per day at $1.0 \mathrm{~atm}$ pressure. What volume tank would be needed to store one day's production at $5.0 \mathrm{~atm}$ ?
