Answer 1

Answer:here is your answer

Solid to liquid= melting

reason= the structure of solid expands when external heat is supplied , the inter molecular force lessens and the particles moves apart causing the solid to melt

Liquid to Solid= Freezing

Reason= when there is loss of heat from a liquid , the constituent particle of the liquid contracts and freezes.

Liquid to Gas= Boiling or vapourisation

reason= it occurs when a liquid is suddenly heated up to its boiling point where it changes to gas or vapourGas to Liquid=condensation

reason= when the gas looses temperature , gases changes to water droplets

Solid to Gas= sublimation

Reason =in this the conversion occurs at a temperature and pressure lower than its triple point.

Gas to Solid = Deposition

Reason= tis usually occurs when thernal or heat energy is removed from the air and the air becomes cold enough .
