177. A supply of 50 kg of chicken at 6°C contained in a box is to be frozen to -18°C in a freezer.

Determine the amount of heat that needs to be removed. The latent heat of the chicken is 247

kJ/kg, and its specific heat is 3.32 kJ/kg-°C above freezing and 1.77 kJ/kg-°C below freezing. Thecontainer box is 1.5 kg, and the specific heat of the box material is 1.4 kJ/kg-°C. Also the

freezing temperature of chicken is -2.8°C.

A. 15,206.4 kJ B. 50.4 kJ

C. 15,156 kJ D. 1,863 kJ
