Homework Statement
A closed, insulated cylinder is divided into two equal parts by a piston. One compartment contains Nitrogen at T=300K, P1=5bar, the other Carbon Dioxide at T=300K, P2=20bar. The cylinder contents then reach mechanical and thermal equilibrium.
1. Assuming that the gases can be treated as ideal gases with heat capacities at constant volume of 5R/2 and 7R/2, obtain the final temperature and pressure.
2. Obtain the final temperature and pressure using accurate thermodynamic properties for N2 and C02
Homework Equations
PV=nRT
ΔU=Q-W
Q=Uf-Ui
Ui=m1u(T1)+m2u(T2)
Uf=(m1+m2)u(Tf)
The Attempt at a Solution
1. Usually for problems like this the first thing you do is find the mass. Since volume is not given, I'm not sure how to even start this problem.
