Answer to Question #208369 in Physics for Trent

Question

A 0.339 kg sample is placed in a cooling apparatus which removes energy as heat at a constant rate. The figure gives the temperature T of the sample versus time t (where the horizontal scale is set by t_s = 80.0 min). The sample freezes during the energy removal. T₁ = 309 K, T₂ = 274 K, T₃ = 216 K, and the specific heat of the sample in its initial, liquid phase is 3012 J/kg K.
