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 -5. C boiling point 35. "C enthalpy of vaporization enthalpy of fusion 6.00 kl/mol 34.00 kJ/mol 2.80 g/em' (solid) 2.40 g/ml. (Nquid) density 46. JK mol (solid) heat capacity 61. J-K mol (liquid) 73. JK mol (vapor) You may also assume X behaves as an ideal gas in the vapor phase. Suppose a small sample of X at -20 C is put into an evacuated flask and heated at a constant rate until 10.0 kl/mol of heat has been added to the sample. Graph the temperature of the sample that would be observed during this experiment. Dat
