An open container holds ice of mass 0.500 kg at a temperature of -16.8 °C. The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 780 J/minute.
The specific heat of ice to is 2100 J/kg⋅K and the heat of fusion for ice is 334×103J/kg.
Part A
Part complete
How much time tmelts passes before the ice starts to melt?
Part B
From the time when the heating begins, how much time trise does it take before the temperature begins to rise above 0°C?
