# Problem: An open container holds ice of mass 0.550 kg at a temperature of -15.3 °C. The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 900 J/minute. The specific heat of ice to is 2100 J/kg⋅K and the heat of fusion for ice is 334 × 103 J/kg.a) How much time tmelts passes before the ice starts to melt?tmelts = ___ minutesb)From the time when the heating begins, how much time trise does it take before the temperature begins to rise above 0 °C?trise = ____ minutes

a)

Qtmelt = mciΔT

tmelt = mciΔT/Q

###### Problem Details

An open container holds ice of mass 0.550 kg at a temperature of -15.3 °C. The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 900 J/minute. The specific heat of ice to is 2100 J/kg⋅K and the heat of fusion for ice is 334 × 103 J/kg.

a) How much time tmelts passes before the ice starts to melt?

tmelts = ___ minutes

b)From the time when the heating begins, how much time trise does it take before the temperature begins to rise above 0 °C?

trise = ____ minutes
