Consider a substance X with a Hvap = 20.3 kj/mol and Hfus = 9.0 kj/mol. The melting point, freezing point, and heat capacities of both the solid and the liquid X are identical to those of water. If you placed one beaker containing 50 g of X at -10 degrees Celsius and another beaker with 50 g of H2O at -10 degrees Celcius on a hot plate and started heating them, which material would reach the boiling point first?

a.) Which of the material from part a, X or H2O, would completely boil away first?

b.) On a piece of graphpaper draw theheating curve for H2O and X. How do the heating curves reflect your answersfrom parts a and b.
