Question

Difference between sublimation and evaporation

Answer 1

Difference between sublimation and evaporation :-

Sublimation :- It's a process of conversion of a substance directly from the solid to the gas state without passing through the liquid state.

Example :- Dry ice or solid carbon dioxide sublimes.

• Sublimation caused by the absorption of heat which provides enough energy of some molecules to basically overcome the attractive forces of their neighbors and escape into the vapour phase.

• Sublimation is a chemical process.

• When ice cubes shrink in the freezer thats also a example of sublimation.

Evaporation :- It's a process of a substance in a liquid state changing to a gaseous state due to the increase in temperature or we can say pressure.

Example :- Water turning into steam.

• Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmosphere water vapour.

• Evaporation is mostly used for instance, extraction of salt from ocean water.
