If 54.0 kJ of heat is gradually added to a 1.00 mol sample of liquid ethanol with an initial temperature of 298 K, the heating curve shown here is obtained. Use this graph to answer the following questions.

a. What is the boiling point?

b. What is the enthalpy of vaporization in kJ/mol?

c. Is the specific heat of liquid ethanol greater than or less than the specific heat of gaseous ethanol? [Section 11.4]
