A gas contained in a steel tank has a pressure of 1.5 atm at a temperature of 320 K.What will be the gas pressure when the temperature changes to 450 K,if the volume and amount of gas do not change?

Question

Quizplus · Accepted Answer

Using the combined gas law:

P1/T1 = P2/T2

where P1 = initial pressure = 1.5 atm

T1 = initial temperature = 320 K

P2 = final pressure = unknown

T2 = final temperature = 450 K

Rearranging this equation to solve for P2:

P2 = (P1/T1) x T2

P2 = (1.5 atm/320 K) x 450 K = 2.1 atm

Therefore, the gas pressure will be 2.1 atm when the temperature changes to 450K.
