An open container holds ice of mass 0.530 kg at a temperature of -15.7 Celsius . The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 810J/minute . The specific heat of ice to is 2100 J/Kg x K and the heat of fusion for ice is 334 x 10^3 j/kg . Part A How much time passes before the ice starts to melt? Part B From the time when the heating begins, how much time does it take before the temperature begins to rise above 0 Celsius?
