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
-20. °C
bolling point
10. °C
enthalpy of
vaporization
enthalpy of fusion
6.00 kJ/mol
29.00 kJ/mol
1.80 g/cm' (solid)
1.70 g/mL (liquid)
density
34. J-Kmol (solid)
heat capacity
38. J-K
mol (liquid)
39. J-K
-1
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 15.0 kl/mol of heat has been added to the sample.
Graph the temperature of the sample that would be observed during this experiment.
