Freezing breаst milk is оne wаy tо preserve the mаcrоnutrients and immune properties in breast milk over time. There are three distinct temperature regions in which breast milk exhibits different thermodynamic properties (above freezing, at freezing, and below freezing). A. Determine the change in enthalpy for 100 mL of breast milk initially at 37ᵒC that will be frozen in a chest freezer at -20ᵒC). The specific heat of breastmilk above freezing (-3ᵒC) is 1.0A cal/(gm*K). The specific heat of frozen milk is .4B cal/(gm*K). The specific latent heat of fusion for breast milk is (70+C) cal/gm. You may assume the density of the milk is uniform and 1.0D gm/mL B. If you need to cool 8 100mL bottles of milk down to -20ᵒC within 24 hours, at what rate must heat be removed (in Watts) from the chest freezer if your tank is 80% efficient?
