Steam can cause more serious burns than water at the same temperature. Here we want to examine this effect quantitatively, noting that flesh becomes badly damaged when its temperature reaches 50.0 oC. (a) Calculate the heat released at 12.5 g of liquid water at 100 oC is cooled to 50.0 oC. (b) Calculate the heat released when 12.5 g of steam at 100 oC is condensed and cooled to 50.0 oC. (c) Find the mass of fresh that can heat from 37 oC (normal body temperature) to 50.0 oC for the cases considered in parts (a) and (b). [The average specific heat of flesh is 3,500 J/(kg K).]
