Emergency rooms in hospitals often have to treat severe cases of skin burn. Compare the severity of the burn inflicted on a person's skin by steam by comparing the heat involved in converting 15 g of steam at 100 C to water at 20 (steam) with the heat involved in cooling the same amount of water (15 g) at 100 C to 20 C (Qwater). Helpful information: Latent heat of vaporization for water, L= 2.428 106 J/kg; Specific heat of water, Cwater = 4,186 J/(kgK); Specific heat of steam, Csteam = 1,996 J/(kgK).
