A 300 mL sample of a gas at a temperature of 400 K exerts a pressure of exactly one atmosphere.
What pressure does the gas exert when the volume
decreases to 200 mL and the temperature increases
to 600 K?

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
