Substance X is known to exist at 1atm in the solid, liquid, or vapor phase, depending on the temperature. Additionally, the values of these other properties of X have been determined (picture). 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 kJ/mol of heat has been added to the sample. Graph the temperature of the sample that would be observed during this experiment.
