Calculate the total amount of energy (in kJ) necessary to raise the temperature of 2.00 L of ethanol (density
= 0.7849 g/cm3
) from 18 0C to its boiling point (78.3 0C) and then to fully vaporize the liquid. Assume that
it is a closed system where no heat exchange with the surroundings take place.
(Given: Cethanol = 2.44 J/g·K; heat of vaporization of ethanol at 78.3 0C = 38.56 kJ/mol.)
The value of heat is
Heat required to vaporize =1315.23kJ
