food product is being frozen in a system capable of removing 6000 kJ of thermal energy. The product has a specific heat of 4 kJ/(kg °C) above the freezing temperature of – 2°C, the latent heat of fusion equals 275 kJ/kg, and the frozen product has a specific heat of 2.5kJ/(kg°C) below –2°C. If 10 kg of product enters the system at 10°C, determine the exit temperature of the product.
