Homework Statement



An ideal gas has the following initial conditions: Vi = 520 cm3, Pi = 3 atm, and Ti = 100°C. What is its final temperature if the pressure is reduced to 1 atm and the volume expands to 1000 cm3?

Homework Equations


I used the equation p1 x v1 / t1 = p2 x v2 / t2


The Attempt at a Solution


3atm x 5.2 m^3 / 100 C = .156
.156 = 1atm x 10 m^3 / T
T= 64.1 C.
This answer was incorrect and I'm wondering if someone could point me in the right direction?? Thanks!!

First of all, you ALWAYS use absolute temperatures with gas law equations.
