8. Gases, Liquids and Solids

A 10.0 L cylinder with a movable piston exerts 3.00 atm of pressure. What will happen to the pressure if the volume of the container increases to 20.0 L?

A sealed container with a movable piston contains a gas with a pressure of 1380 torr, a volume of 820 mL and a temperature of 31°C. What would the volume be if the new pressure is now 2.83 atm, while the temperature decreased to 25°C?

a. The diaphragm contracts.

Use the words inspiration and expiration to describe the part of the breathing cycle that occurs as a result of each of the following:

c. The pressure within the lungs is higher than that of the atmosphere.
