Substance X is known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperature. Additionally, the values of these other properties of X have been determined: melting point enthalpy of fusion density 75. "C 8.00 kJ/mol 2.80 g/cm (solid) 2.30 g/ml.

Suppose a small sample of X at 50 °C is put into an evacuated flask and heated at a constant rate until 6.0 kJ/mol of heat has been added to the sample. Graph the temperature of the sample that would be observed during this experiment.
