Ethanol, C₂H₅OH, boils at 78.29°C. How much energy, in joules, is required to raise the temperature of 1.00 kg of ethanol from 20.0°C to the boiling point and then to change the liquid to vapor at that temperature? (The specific heat capacity of liquid ethanol is 2.44 J/g ∙ K, and its enthalpy of vaporization is 855 J/g.)
