A balloon filled with 39.1 moles of helium has a volume of 876 L at 0.0∘C and 1.00 atm pressure. At constant pressure, the temperature of the balloon is increased to 38∘C, causing th e 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 J∘C1mol−1.)
