Q4
A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A Chemist collects a sample of the gas with the idea of trying to identify the gas. The wet gas collected occupies a volume of 291 mL at a pressure of 789 torr and temperature of 28.0oC. The vapour pressure of water at 28.0oC is 0.0372 atm. Calculate the volume (L) that the gas occupies after it is dried (the water vapor removed) and stored at STP.

Q5
A gas in a cylinder held at a constant pressure of 1.7×105 Pa and is cooled and compressed from 1.20m3to0.8m3. The internal energy of the gas decreses by 1.1×105 J.
Does it matter whether or not the gas is ideal? Mark 1->Yes and 0->No
