At a birthday party,a student ate a piece of cake (food energy value of 400 calories).To prevent this energy from being stored as fat,she decides to drink ice water at 0 C.She reasons that the ingested ice water will be warmed up to her normal body temperature of 37 C and absorb the energy.How much ice water would she have to drink to absorb the energy generated by metabolizing the birthday cake?

specific heat of water:1 cal/g*℃
400/[1*(37-0)]=10.81 g
