1) Frozen shrimp. 140 kg of shrimp at 20C contained in a box is to be frozen to -18C in a freezer. Determine the amount of heat that needs to be removed. The latent heat of the shrimp is 280 kJ/kg, and its specific heat is 3.8 kJ/kgC above freezing and 2.2 kJ/kgC below freezing. Freezing temperature of shrimp is -2C. The container box is 10.2 kg and is made up of polyethylene, whose specific heat is 2.3 kJ/kgC
