Question

Your high-powered microwave oven heats a frozen dinner to a temperature of 180.0°C, which you find is too hot to eat comfortably. To cool the dinner, you place a 0.250 kg frozen dinner (mostly solid) at 180.0°C into a 0.450-kg ceramic plate that is initially at room temperature (25.0°C). What is the final temperature of the dinner and plate? Assume that the dinner and plate are thermally isolated. Express your answer in degrees Celsius. Assume • Specific heat capacity of the frozen dinner ($c_{dinner}$): 2090 J/kg°C • Specific heat capacity of the ceramic plate ($c_{ceramic}$): 840 J/kg°C Your Answer: Answer units
