Question

What is the link between cohesive force and evaporation?

Answer 1

Relation between cohesive force and evaporation:

1. The force of attraction between molecules of the same type is called cohesive force.
2. Ex: the cohesive force between water molecules keeps them bonded together, etc.
3. The process through which the liquid state of matter is transformed into the gaseous state of matter is called evaporation.
4. Ex: evaporation of acetone when placed on palm, etc.
5. Evaporation is a surface phenomenon and cohesive force also indirectly depends on surface tension.
6. Cohesive force helps in reducing the surface tension of the liquid and also the evaporation rate.
