A 1.41-kg aluminum pot contains 2.25 L of water. Both pot and water are initially at 17.5°C. How much heat must flow into the pot and the water to bring their temperature up to 92.7°C? Assume that the effect of water evaporation during the heating process can be neglected and that the temperature remains uniform throughout the pot and the water.
use the following values for the specific heats:
c_water=4.19 kJ/kg.K
c_aluminum=0.900 kJ/kg.K
