A water heater has a power of 800 watts. It is connected to 220 volts and then submerged in 20 liters of water having an initial temperature of 15 o C The watercontainer absorbs 100% of the heat developed. Neglecting heat lost to thesurrounding air, how much time will it take for the water to reach a temperature of60°C?
0.165 kg of water at 88.0o C is poured into an insulated cup containing 0.204 kg of ice initally at 0o. Calculate the mass of liquid when the system reaches thermal equilibrium.
What is the COP of a freezer rated at 200.0 Watts if it takes 30.0 minutes to convert 3.90 kg of water at 25.0 degrees celsius into ice at 0.00 degrees celsius? (Assume all evergy as heat removed from the appliances cold compartment is removed from the water.)
