Three liquid samples of known masses are heated to their boiling points with the use of a heater rated at 500.0 W. Once the boiling points of each sample are reached, the samples are heated for an additional 4.96 min, which results in the vaporization of some of each sample. After 4.96 min, the samples are cooled and the masses of the remaining liquids are determined. The process is performed at constant pressure. The results are recorded in the table.

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 I have been determined: melting point enthalpy of fusion temperature (°C) 120- 110- 100- 90- 80 70- 60- You may also assume X behaves as an ideal gas in the vapor phase. Suppose a small sample of X at 20 °C is put into an evacuated flask and heated at a constant rate until 10.0 kJ/mol of heat has been added to the sample.
