Sketch a heating curve for a substance X whose melting point is 40 degrees Celcius and whose boiling point is 65 degrees Celcius.

a. Describe what you will observe as a 60.0 g sample of X is warmed from 0oC to 100oC.

b. If the heat of fusion os X is 80.0 J/g, the heat of vaporization is 190.J/g, and if 3.5 J are required to warm 1 g of X each degree, how much energy will be needed to accomplish the change in a?
