An open container holds ice of mass 0.580kg at a temperature of -18.8∘C . The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 870 J/minute.

The specific heat of ice to is 2100 J/kg⋅K and the heat of fusion for ice is 334×103J/kg.

How much time t melts passes before the ice starts to melt?

From the time when the heating begins, how much time t rise does it take before the temperature begins to rise above 0∘C?
