A balloon filled with 39.1 mol helium has a volume of 876 L at 0.0 C and 1.00 atm pressure. The temperature of the balloon is increased to 38.0 C as it expands to a volume of 998 L, the pressure remaining constant. Calculate q, w, and U for the helium in the balloon. (The molar heat capacity for helium gas is 20.8 J/ C .mol.)
