A balloon filled with 35.6 moles of helium has a volume of 856 L at 0.0°C and 1.00 atm pressure. The temperature of the balloon is increased to 43.0°C as it expands to a volume of 967 L, the pressure remaining constant. Calculate q, w, and ΔE for the helium in the balloon. (Given, the molar heat capacity for helium gas is 20.8 J/°C · mol, and 1 L·atm = 101.3 J) (Show your work)
