Question

Which of the following phenomena always results in the cooling effect?
(a) Condensation (b) Evaporation (c) Sublimation (d) Melting

Answer 1

Answer:

Hello my friend

Explanation:

Evaporation produces colouring as the particles at the surface of the liquid gain energy from the surroundings and change into vapour therefore producing a cooling effect

Answer 2

Out of the following evaporation has a cooling effect.

Option b

Explanation:

• Evaporation can be stated as an example of surface phenomena while boiling is an example of  bulk phenomena.

• during evaporation a liquid is converted into a gaseous state at a temperature which is below the boiling point of a liquid.

• Whereas in case of boiling the change takes place only at the boiling point. The amount of heat which is required for boiling is more because there is additional latent heat which is involved.

• In case of boiling the change takes place in all parts of the liquid

• Whereas in evaporation the change takes place only at the surface of the liquid and as a result of this it is defined as the surface phenomena.
