Explain how much heat energy is necessary to heat

Reference no: EM13655624

Ethanol, C2H5OH, boils at 78.29°C. How much heat energy (in kilojoules) is necessary to heat 1.30 kg of this liquid from 19.0°C to the boiling point also then change the liquid totally to a vapor at that temperature? The specific heat of liquid ethanol is 2.44 J/g•K as well as its enthalpy of vaporization is 38.56 kJ/mol.
