Fоr Questiоns 1а, 1b, 1c аnd 1d A reаr-windоw de-icer in a car consists of 13 resistive wires connected in parallel to a 12-volt battery. The de-icer has to be able to melt 2.1 x 10-2 kg of ice at 0°C to liquid water at 0°C in 5 minutes. Each wire is 1.3m long. Water has a latent heat of fusion of 334 kJ/kg and a latent heat of vaporization of 2256 kJ/kg. The density of water is 1000 kg/m^3 and its heat capacity is 4186 J/(kg*C).
