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 -25. °C boiling point 35. °C enthalpy of vaporization enthalpy of fusion 8.00 kJ/mol 46.00 kJ/mol 3.00 g/cm (solid) 2.40 g/mL (liquid) density 40. J-K -1 -1 *mol (solid) -1 heat capacity 28. J-K *mol (liquid) 71. 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 8.0 kJ/mol of heat has been added to the sample. Graph the temperature of the sample that would be observed during this experiment.
