Test: Evaporation And Condensation - Question 1

Transpiration from the leaves of trees is an example of:

Detailed Solution: Question 1

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves.

Test: Evaporation And Condensation - Question 2

Natural phenomenon like fog, mist or frost are caused due to:

Detailed Solution: Question 2

Fog, mist or frost are due to condensation, depending upon the physical conditions of atmosphere.

Test: Evaporation And Condensation - Question 3

Which statement regarding the effect of humidity on evaporation is correct?

Detailed Solution: Question 3

Humidity refers to presence of vapour in air. So, if humidity increases then the rate of evaporation decreases as vapours in air are already present.

Test: Evaporation And Condensation - Question 4

Evaporation of a liquid takes place at temperature:

Detailed Solution: Question 4

Correct option is D. 
Evaporation is the process of a liquid turning into vapor at any temperature below its boiling point. During evaporation, particles escape from the surface of the liquid to form gas. Evaporation is different from boiling because it only occurs at the surface of the liquid and is very slow. 

Test: Evaporation And Condensation - Question 5

 Evaporation occurs at the surface of a liquid because the particles at the surface:

Detailed Solution: Question 5

Correct answer is A. 
Evaporation occurs at the surface of a liquid because the particles at the surface have sufficient energy to break through the forces of attraction between them.
