Heat needed to melt the ice is equal to mc?? +ml.Ice has a specific heat capacity of 2100J/kg K.336 000 J/kg is the specific latent heat of fusion of ice.Volume of ice =&amp;nbsp;4.7×10−4×1.25=5.875×10−4m3&amp;nbsp;mass of ice = density * volume =&amp;nbsp;5.875×10−4×917=0.5387kg&amp;nbsp;Amount of heat required&amp;nbsp;=0.5387×2100×(10.6−0)+0.5387×336000=193000J
