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 9.00 kJ/mol 2.40 g/cm³ (solid) 2.20 g/mL. (liquid) boiling point enthalpy of vaporization heat capacity 115. "C 36.00 kJ/mol 25. J-K mol (solid) -1 40. JK mol (liquid) 42. JK mol (vapor) You may also assume X behaves as an ideal gas in the vapor phase. 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.
