2/28 HW – Gas Laws Review
1. List the four variables that describe a gas and corresponding
units for the variable.
2. The gas in
14.0 L container exerts a pressure of 115 kPa. What pressure is needed to compress the gas
to 2.0 L while keeping the temperature constant?
3. The gas
left in a used aerosol can is at a pressure of 100 kPa
at 27˚ C. If the can is thrown into
a fire, what will the internal pressure of the gas be when its temperature
reaches 1000˚ C?
4. A helium
balloon has a volume of 450 mL at a temperature of
45˚ C. What will be the volume of
the balloon if you take the balloon to
5. A
pressurized gas container has a volume of 3.5 L at a temperature of 22˚ C. If the container contains 4.56 kg of oxygen,
what is the pressure inside the container?
