(a)
A tank contains one mole of nitrogen gas at a pressure
of 6.85 atm and a temperature of 31.5°C. The
tank (which has a fixed volume) is heated until the pressure inside
triples. What is the final temperature of the gas?
°C
(b)
A cylinder with a moveable piston contains one mole of nitrogen,
again at a pressure of 6.85 atm and a temperature
of 31.5°C. Now, the cylinder is heated so that both the
pressure inside and the volume of the cylinder double. What is the
final temperature of the gas?
°C
