A gas is heated from 298 K to 367 K while its volume changes from 2.5 L to 3.9 L. If the initial pressure of the gas is 1.1 atm, what is the final pressure of the gas?

This problem can be solved using one of the different gas laws, which is shown below:

PV/T

Given:

P1 = 1.1 atm
V1 = 2.5 L
T1 = 298 K

P2 = ?
V2 = 3.9 L
T2 = 367 K

Substituting the given:

P1V1/T1 = P2V2/T2

(1.1 2.5)/298 = (P2 3.9)/367
P2 = 0.868 atm
