Thanks. I worked through the #2 and 3 and I am all set with those two. But I cannot get the first problem right. To find heat, I used Q=nCp(deltaT) and with W=0. then plugged into Q=(delta U) + W. Is there something that I am doing wrong?

1. Cylinder contains 0.1 mol of ideal gas at a pressure of 2 atm and temperature of 300 K. The volume of the cylinder is 1.25 x 10^-3 m3. When the gas is heated from 300K to 350K, what is the change in internal energy of the gas? --->(I think the equation is Q=delta U + W but I don't know...
