### Discussion 1J worksheet- Question 8

The question is: A cylinder fitted with a frictionless piston contains 3.00 mol of He gas at P=1.00 atm and is in a large constant -temperature bath at 400 K. The pressure is reversibly increased to 5.00 atm. Find w, q, and U for this process?

Can someone help?!

Because the volume is held constant (Delta V=0), the gas cannot perform any work; thus, w=0 and delta U=q.
