A ceramic mug has a mass of 200 g. It is initially at room temperature, 20ºC. It is filled with 100 g of hot coffee at 90 ºC. Assuming no heat it lost to the environment, what is the temperature of the coffee after the cup and coffee come to thermal equilibrium? ccoffee = 1 cal/g ºC cceramic = 1090 J/kg ºC
