Question

Two solids A (melting point = 90 ˚C) and B (melting point = 190 ˚C) are provided.
i. Which solid has lesser forces of attraction?
ii. Which solid will absorb higher amount of Latent heat of Fusion for melting?

Answer 1

Dear student, I.) Solid A has lower boiling point which means intermolecular forces of attraction are week/lesser than solid B. II.) Lattern heat of fusion will be higher for solid B because since boiling point is higher more energy is required to convert it from solid to liquid. Regards,
