A beaker of negligible heat capacity contains 456 g of ice at -25.0°C. A lab technician begins to supply thermal energy through the process of heating to the container at the rate of 1000 J/min
How long after starting will the ice begin to melt, assuming all of the ice has the same temperature? The specific heat of ice is 2090 J/kg ? K and the latent heat of fusion of water is 33.5 × 104 J/kg.
