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
Enthalpy of fusion 9.00 KJ/mol
Density 2.40 g/cm^3
1.80 g/ml

Boiling point 65°C
Enthalpy Of vaporization 23.00 KJ/mol
Heat capacity 38 J. K^-1 mol^-1
28 J. K^-1 mol^-1
64 J. K^-1 mol^-1

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 kJ/mol of heat has been added to the sample.

Requried:
Graph the temperature of the sample that would be observed during this experiment.
