Question

A cyclinder fitted with a piston holds 8.07g CH4 in 7.05L at -8C. While heating the gas at 1.55atm, 366 of heat was added. What is the change in internal energy during the heating?

R = 0.08206 L-atm/K-mol = 8.314 L-kPa/K:mol = 62.36 L·Torr/K-mol = 8.314 J/K-mol
1 L-atm = 101.325 J
Swater = 4.184 J/g.°C
Siron = 0.444 J/g.°C
Smethane = 2.07 J/g.°C
