Question:
A 0.400 kg sample is placed in a cooling apparatus that removes energy as heat at a constant rate. Figure gives the temperature T of the sample versus time t; the horizontal scale is set by ts = 80.0 min. The sample freezes during the energy removal. The specific heat of the sample in its initial liquid phase is 3000 J/kg ? K. What are? br> (a) The sample's heat of fusion and br> (b) Its specific heat in the frozen phase?br>
