An ideal monatomic gas expands isothermally from 0.590 m3 to 1.25 m3 at a constant temperature of 780 K. If the initial pressure is 1.20x10^5 Pa.
(a) Find the work done on the gas.
(b) Find the thermal energy transfer Q.
(c) Find the change in the internal energy.
PfVf/PiVi = Tf/Ti
The Attempt at a Solution
I know I need to find the final pressure...but I'm not sure how to.
Do I use Pf*1.35/1.2x10^5 = 780k?
