Question

One mole of oxygen gas is at a pressure of 5.10 atm and a temperature of 32.0°C.
(a) If the gas is heated at constant volume until the pressure triples, what is the final temperature?

Answer 1

P V = n R T

V, n and R are constant in this case.

If the pressure P triples at constant volume, so does the absolute termperature, T. It goes from 305 K to 915 K. Convert that back to C, if you wish.
