A 1.70-kg piece of aluminum that has a temperature of −147 °C is added to 1.00 kg of water that has a temperature of 3.1 °C. At equilibrium the temperature is 0.0°C. Assuming that the heat exchanged with the container and the surroundings is negligible, determine the mass of water that has been frozen into ice.
Specific heat of aluminum = C1 = 900 J/(kg.oC)
Specific heat of water = C2 = 4186 J/(kg.oC)
Latent heat of fusion of water = L = 334000 J/kg
Mass of the piece of aluminum = m1 = 1.7 kg
Mass of water = m2 = 1 kg
Initial temperature of aluminum = T1 = -147 oC
Initial temperature of water = T2 = 3.1 oC
Final equilibrium temperature = T3 = 0 oC
Mass of water that has been frozen into ice = m3
The heat gained by the piece of aluminum is equal to the heat lost by the water.
m3 = 0.635 kg
Mass of water that has been frozen into ice = 0.635 kg
