Question

On heating a sublimable solid, the molecules break free & escape from surface of the solid directly into vapour. why

Answer 1

answer : On heating a sublimable solid the inter-particle attraction is overcome and the molecules break-free and escapes from the surface of the solid directly into the vapour.

Answer 2

Answer:

On  heating a sublimable solid, the molecules break free and escape from the surface of the solid directly into vapor because, due to heating, kinetic energy of the molecules will increase and the particle's intermolecular attraction decreased so that they can easily transfer into vapor.

Explanation:

What is sublimation and sublimable solid?

• Sublimation is a process in which a solid compound gets directly converted into gas without undergoing the liquid phase.

• Sublimable solid is a compound which can easily undergo into sublimation process.

• Examples of sublimation are camphor, dry ice, naphthene balls, etc.

• During the sublimation of a sublimable solid on heating, the kinetic energy of molecules will increase and the intermolecular attraction between molecules break downs and escapes from the surface of the solid into directly vapor.
