For preservation over long durations (years), bacterial cultures are sometimes stored at -70 C. Evaluate how much heat one needs to add to thaw 1 g of such a sample to room temperature (25 C). You may assume that the cells behave mostly like water. Specific heat capacities (Cp) of water and ice are 4200 kJ/kg-K and 2100 kJ/kg-K, respectively, and the heat of fusion of ice is 333 J/g.
