Question

An open container holds ice of mass 0.590 at a temperature of -14.0 . The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 770 j/min.
The specific heat of ice to is 2100 j/kg and the heat of fusion for ice is 332x10^3 j/kg.


How much time Tmelts 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?


I need to show my work. please help me with this problem

Explanation / Answer

Assuming no heat loss, t_melts ˜ (0.505 kg)(2,100 J/ kg°C)(14°C)/(800 J/min.) t_melts ˜ 18.55875 min. ˜ 18.6 min. t_rise ˜ 18.6 min. + (0.505 kg)(334e+3 J/kg)/(800 J/ min.) t_rise ˜ 18.6 min. + 210.8 min. t_rise ˜ 229.4 min.
