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 80. °C boiling point 120. °C enthalpy of vaporization enthalpy of fusion 7.00 kJ/mol 34.00 kJ/mol 1.60 g/cm (solid) 1.40 g/mL (liquid) density 48. J-K.mol (solid) heat capacity 61. J.K.mol (liquid) 82. J-K.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 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. 150- 140- 130- 120- 110- 100- 90- 80 70 60- 50+ 10 15 heat added (kJ/mol) temperature (°c)
