Why is the heat of fusion (AH) of a substance smaller than its heat of vaporization (AH,ap)? Why is the heat of sublimation (AH) of a substance greater than its heat of vaporization(AH,ap)? Add the heats of fusion and vaporization. Compare this number with the heat of sublimation. Why do you notice? Explain this.
