A cylinder used in a lab contains a gas at 7.59 atm and 27 oC. What would the pressure of the gas be if the temperature changed to 77 oC?

Question

the solution to the problem

Answer 1

P1 = initial pressure =7.59 atm

T1 = initial temperature in K = 27C + 273 = 300K

P2 = final pressure = ?

T2 = final temperature in K = 77C + 273 = 350K

At constant volume, we can use P1/T1 = P2/T2

7.59 / 300 = P2 / 350

P2 = 8.86 atm
