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: temperature ("C) melting point enthalpy of fusion E density 130- DE 120- 118- 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. IM- 00 75. "C 8.00 kJ/mol 2.80 g/cm² (solid) 2.30 g/ml.
