Consider the heating curve provided for 1.00 mole of a substance that begins as a solid at -14.8 °C and ends as a gas at 121.1 °C.
Specific heat capacities: solid = 145.6 J/mol·°C, liquid = 97.25 J/mol·°C, gas = 68.49 J/mol·°C
Step B: How much heat energy (in kJ) must be absorbed to melt the solid?
