If a food product is being frozen in a system capable of removing 6200 kJ of thermal energy per product, with the product having a specific heat of 4.1 kJ/kg°C above the freezing temperature of -1.7°C , a latent heat of fusion of 284 kJ/kg, and the product has a specific heat of 2.2 kJ/kg°C below the freezing temperature. If 10.1 kg of product enters the system at 15°C, and exits it with a temperature of –12 °C, what percentage (to the nearest percent) of the full capability of the freezer has been used?
