A balloon filled with 39.1 moles of helium gas has a volume of 876 L at 0.0Â°C and 1.00 atm pressure. At constant pressure, the temperature of the balloon is increased to 38.0Â°C causing the balloon to expand. Calculate q, w, âE for the helium in the balloon. The specific heat of helium gas is 5.20 J/(g Â°C) and 101.3 J = 1 Latm.
