You pour 160 g hot coffee at 78.7°C and some cold cream at 7.50°C to a 115-g cup that is initially at a temperature of 22.0°C. The cup, coffee, and cream reach an equilibrium temperature of 63.0°C. The material of the cup has a specific heat of 0.2604 kcal/(kg• °C) and the specific heat of both the coffee and cream is 1.00 kcal/(kg · C). If no heat is lost to the surroundings or gained from the surroundings, how much cream did you add? 0.039 X Does the coffee lose or gain heat? Does the cup lose or gain heat? What about the cream? How is the net quantity of heat gained related to the net quantity of heat lost? g Additional Materials Reading
