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 one vial of 100 mL of breast milk initially frozen at -18ᵒC that will be thawed to body temperature 37ᵒC . The specific heat of breast milk above freezing (-3ᵒC) is 1.0C cal/(gm*K). The specific heat of frozen breast milk is .4D cal/(gm*K). The specific latent heat of fusion for breast milk is (70+A) cal/gm. You may assume the density of the breast milk is uniform and 1.0B gm/mL. B. If you warm 3 100mL bottles of breast milk to 37ᵒC within 4 minutes, at what rate (in Watts) must heat be added to the system if your heater is 70% efficient?
