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: 140. "C melting point enthalpy of fusion 95. C 6.00 kJ/mol 2.40 g/cm (solid) 2.10 g/mL. (liquid) boiling point enthalpy of vaporization 48.00 kJ/mol density heat capacity -1 28. JK mol (solid) 41. J-K-mol(liquid) 41. 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 10.0 kJ/mol of heat has been added to the sample. Graph the temperature of the sample that would be observed during this experiment. 10 10 x 2 temperature (C) 100 10
