A large room contains a volume of air of Va = 15 m3 at a temperature of Ta = 53° F. It also contains a bathtub holding a volume of water of Vw = 0.56 m3 at a temperature of Tw = 101° F. Calculate the final temperature of the system in kelvin, assuming a constant specific heat for the water of cw = 4180 J/kg⋅K and a constant specific heat capacity for the air of ca = 1010 J/kg⋅K. Calculate the change in the internal energy ΔU of the room-water system in joules.
