3. A substance, X, has the following properties: AHvap AHtus bp 20 kJ/mol 5.0 kJ/mol 75 C -15 C Specific Heat Capacities X (s) 3.0 J/g C 2.5 Jig C X (9) 1.0 J/gC X() mp Sketch a heating curve for substance X starting at -40C and ending at 90*C. Use the enthalpy numbers and specific heat capacities to be qualitatively (relative) accurate, but not quantitatively accurate. For instance, for a given amount of substance X, more heat will be required to fully vaporize the amount than it will take for fusion because of the relative enthalpy numbers. The specific-heat capacity is the energy required to raise the temperature of one gram of substance one degree Celsius
