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 6.00 g of 100°C water to lower its temperature to 48.0°C.

(b) Calculate the heat (in kcal) that must be removed from 6.00 g of 100°C steam to condense it and lower its temperature to 48.0°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 48.0°C. (Flesh is badly damaged at 50.0°C.)

Steam:______kg

Water: _______kg

Steam at 100.°C was passed into a flask containing 360.0 g of water at 21°C where the steam condensed. How many grams of steam must have condensed if the temperature of the water in the flask was raised to 78°C? The heat of vaporization of water at 100.°C is 40.7 kJ/mol, and the specific heat is 4.18 J/(g·°C).
