Problem: The volume of a sample of a fixed amount of gas is decreased from 2.0 L to 1.0 L. The temperature of the gas in Kelvins is then doubled.What is the final pressure of the gas in terms of the initial pressure?

FREE Expert Solution

We are asked to determine what will be the pressure of a gas, in connection to the initial pressure, for which the volume is increased from 2.0 L to 1.0 L while temperature, in Kelvin, is doubled.


Recall that the ideal gas law is:


PV = nRT



The pressure, volume, and temperature of a gas are related to the number of moles of gas and the universal gas constant:


PVT= nR
