5. A 500 W water heater, connected to a 120 V DC power source, is submerged in a bucket containing 10 liters of water and 2 kg of ice. а. How much heat is transferred from the heater to the water, every second? b. How long will it take for all the ice to melt? Properties of water: density p=1 kg/l; specific heat capacity c=4186 J/(kg ºC); latent heat of fusion L=3.35x105 kg/J; latent heat of vaporization L,=2.26×10°J/kg.
