Question

Heat needed to convert a tightly bound solid to a loosely bound liquid.(one word answer ​

Answer 1

Heat needed to convert a tightly bound solid to a loosely bound liquid is called the latent heat of fusion.

Answer 2

Latent- Heat- of -fusion convert the tightly bound solid into loosely bound liquid

Explanation:

• On heating, solid the tightly bound molecule in solid get loose and results into liquid.

• Amount of the heat that is required to convert tightly bound solid into liquid is called as Latent- Heat-of -fusion.

• On heating, it expands because the motion of molecule get increase so their distance between each other increase that's  why it expands.
• In expansion volume gets increase
