A gas tanker is carrying 325,875 L of octane, C8H18, at 965 mm Hg. What is the volume of the propane at standard pressure?

3

The temperature inside Mark's fridge is about 3°C. If he places a balloon in the fridge that initially has a temperature of 25°C and a volume of 1,5 L , what will be the volume of the balloon when it is fully cooled by the refrigerator?

3

Two boys have a gas in a sealed container at a pressure of 5,25 atm at 32°C. A warning on the can tells them not to store the can in a place where the temperature will exceed 65°C but they place it in a hot area anyway. What would the gas pressure in the container be at 65°C

Initially, a gas is at a pressure of 23 atm, a volume of 18 L, and a temperature of 186 K. Then the pressure is increased to 39 atm and the temperature is increased to 398 K, what is the new volume of the gas?
