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 -40. °C boiling point - 10. °C enthalpy of vaporization enthalpy of fusion 5.00 kJ/mol 43.00 kJ/mol 圖 2.90 g/cm ³ (solid) density 37. J'Kmol -1 (solid) 2.50 g/mL (liquid) heat capacity 25. J·K'mol (liquid) 49. J'Kmol (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 15.0 kJ/mol of heat has been added to the sample. Graph the temperature of the sample that would be observed during this experiment.
