A 0.750 L quantity of steam condensed on a surface (after boiling).

a. Approximately how much heat has evolved?

By using the change in enthalpy of vaporization is 40.7 kjmol^-1 for water at 100 C, 85.0 C as the temperature of the surface on which the steam condenses, and 4.21 J g^-1 C^-1 as the average specific heat of liquid water in the temperature ranges 85C to 100C. b. How much heat has evolved in this case?
