Question: A food product is being frozen in a system with capacity remove 6000kJ of thermal energy. Assume the product has a specific heat of 3.5 kJ/ (kg degrees Celsius) above the initial freezing temperature of -2 degrees, a latent heat of fusion of 275 kJ/kg, and a specific heat of 2.8 kJ/ (kg degrees Celsius) for the frozen product below -5 degrees Celsius.
Part A: Estimate the final temperature of 15 kg of frozen product, if the initial temperature is 20 degrees Celsius?
Please explain clearly with details so that I can follow.
