An open container holds ice of mass 0.585 kg at a temperature of -12.1 degreesC. The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 770 J/minute The specific heat of ice to is 2100 J/kg⋅K and the heat of fusion for ice is 334×103J/k
How much time Tmelts passes before the ice starts to melt?
From the time when the heating begins, how much time trise does it take before the temperature begins to rise above 0degreesC?
