Burns produced by steam at 100°C are much more severe than those produced by the same mass of 100°C water. To verify this, do the following.
(a)
Calculate the heat (in kcal) that must be removed from 5.00 g of 100°C water to lower its temperature to 50.0°C.
(b)
Calculate the heat (in kcal) that must be removed from 5.00 g of 100°C steam to condense it and lower its temperature to 50.0°C.
(c)
Calculate (in kg) the mass of human flesh that the heat produced in each case can raise from the normal 37.0°C to 50.0°C. (Flesh is badly damaged at 50.0°C.)
