ocean while it was underwater (pressure of 15.75 atm), what would be the new volume
of the air inside?
11. A man heats a balloon in the oven (Why?who knows?...it is a crazy world we live in).
If the balloon initially has a volume of 0.40 L and a temperature of 20 °C, what is its

12. A gas has a pressure of 1.26 atm and occupies a volume of 7.40 L. If the gas is
compressed to a volume of 2.93 L, what is its new pressure?
13. People who are angry sometimes say that they feel as if they'll explode. If a calm
person with a lung capacity of 3.5 liters and a body temperature of 36 °C gets angry,
what is the volume of their lungs if their temperature rises to 39 °C. Do you think they
will really explode?
