Question

A balloon filled with 39.1 moles of helium has a volume of 876 L at 0.08C and 1.00 atm pressure. At constant pressure, the temperature of the balloon is increased to 38.08C, causing the balloon to expand to a volume of 998 L. Calculate q, w, and ΔE for the helium in the balloon. (The molar heat capacity for helium gas is 20.8 JoC-1mol-1.)
