1. A gas occupies a rigid 55.0 liter container at 29.5°C and 312 kPa. Assuming
cannot change, what temperature (in Celsius) is needed to give a pressure of 500. kPa?

2. A balloon containing 3.55 liter of air at 310 kelvin is then placed in a freezer. The temperature inside the freezer measures 258 kelvin. What will the balloon's volume become at 258 kelvin?

3. A gas occupies 155 liter at 22°C and 952 mm Hg. What is the volume of the same gas
at STP? (STP: T=0°C or 273 K,
P = 1.00 atmosphere = 760. mm Hg = 101 kPa)

4. A 3.50 L sample of 20.0°C and a pressure of 86.7 kPa expands to a volume of 8.00 L and a pressure of 56.7 kPa. What is the final temperature of the gas in Celsius?


5. A bubble of oxygen at the bottom of the ocean has a volume of 0.10 ml, at a pressure of 1.75 atm and temperature of 10.0°C. What will be the volume of this bubble (in ml) at sea level if the temperature is 15°C and a pressure of 1.00 atm?
