Problem

Suppose you have a fixed amount of an ideal gas at a constant volume.

If the pressure of the gas is doubled while the volume is held constant, what happens to its temperature? [Section 10.4]

Solution

We’re asked to determine what happens to the temperature of a fixed amount of an ideal gas at a constant volume when its pressure is doubled.


Recall that the ideal gas law is:


PV=nRT


The pressure and temperature of a gas are related to the number of moles, gas constant and temperatureThe value nR/V is constant:


PT=nRV
