A gas at 155 kPa and 25°C occupies a container with an initial volume of 1.00 L. By changing the volume, the pressure of the gas increases to 605 kPa as the temperature is raised to 125°C. What is the new volume if the number of moles is constant?

The new volume is =0.34L

Explanation:

Apply The ideal Gas Law

PV=nRT

PVT=nR=constant, The number of moles is constant.

P1V1T1=P2V2T2

The initial pressure is P1=155kPa

The initial temperature is T1=25C+273=298K

The initial volume is V1=1L

The final pressure is P2=605kPa

The final temperature is T2=125C+273=398K

The final volume is

V2=P1P2T2T1V1

=1556053982981

=0.34L
