Q. A 3.85 102 g glass coffee cup is at room temperature, 20.0°C. It is then plunged into hot dishwater, 82.0°C. If the temperature of the cup reaches that of the dishwater, how much heat does the cup absorb? Assume the mass of the dishwater is large enough so its temperature doesn't change appreciably.
