Assertion : Melting of solid causes no change in internal energy.
Reason : Latent heat is the required to melt a unit mass of solid.

(A) : Melting of solid causes no change in internal energy. ( R) : Latent heat is the heat required to melt a certain mass of solid.

Define melting point of solid?

A: The internal energy of a solid substance increases during melting. R: Latent heat is required to melt a solid substance.

A: The internal energy of a solid substance increases during melting. R: Latent heat is required to melt a solid substance.

Silica is high melting solid, because
