Physics

An open container holds ice of mass 0.570 kg at a temperature of-13.7 ∘C. The mass of the container can be ignored. Heat issupplied to the container at the constant rate of 730 J/minute. Thespecific heat of ice to is 2100 J/kg⋅K and the heat of fusion forice is 334×10^3 J/kg.

A) How much time [tmelts] passes before the ice startsto melt?
B)From the time when the heating begins, how much time [trise]doesit take before the temperature begins to rise above 0∘C?
