Why is the heat of fusion of a substance smaller than its heat of vaporization?

Chloroform, $\mathrm{CHCl}_3$, a volatile liquid, was once used as an anesthetic but has been replaced by safer compounds. Chloroform boils at $61.7^{\circ} \mathrm{C}$ and has a heat of vaporization of $31.4 \mathrm{~kJ} / \mathrm{mol}$. What is its vapor pressure at $36.2^{\circ} \mathrm{C}$ ?

Steam at $100^{\circ} \mathrm{C}$ was passed into a flask containing $275 \mathrm{~g}$ of water at $21^{\circ} \mathrm{C}$, where the steam condensed. How many grams of steam must have condensed if the temperature of the water in the flask was raised to $83^{\circ} \mathrm{C}$ ? The heat of vaporization of water at $100^{\circ} \mathrm{C}$ is $40.7 \mathrm{~kJ} / \mathrm{mol}$ and the specific heat is $4.18 \mathrm{~J} /\left(\mathrm{g} \cdot{ }^{\circ} \mathrm{C}\right)$.

A quantity of ice at $0^{\circ} \mathrm{C}$ is added to $64.3 \mathrm{~g}$ of water in a glass at $55^{\circ} \mathrm{C}$. After the ice melted, the temperature of the water in the glass was $15^{\circ} \mathrm{C}$. How much ice was added? The heat of fusion of water is $6.01 \mathrm{~kJ} / \mathrm{mol}$ and the specific heat is $4.18 \mathrm{~J} /\left(\mathrm{g} \cdot{ }^{\circ} \mathrm{C}\right)$.

Water at $0^{\circ} \mathrm{C}$ was placed in a dish inside a vessel maintained at low pressure by a vacuum pump. After a quantity of water had evaporated, the remainder froze. If $9.31 \mathrm{~g}$ of ice at $0^{\circ} \mathrm{C}$ was obtained, how much liquid water must have evaporated? The heat of fusion of water is $6.01 \mathrm{~kJ} / \mathrm{mol}$ and its heat of vaporization is $44.9 \mathrm{~kJ} / \mathrm{mol}$ at $0^{\circ} \mathrm{C}$.
