Question

What is not true about evaporation?
(A) Greater the surface area of the liquid, the quicker the evaporation.
(B) Evaporation produces cooling.
(C) Evaporation takes place at all temperatures
(D) Evaporation is nothing but at the highest temperature of the liquid.

Answer 1

For answering this question, we have to know some properties of the evaporation, So in evaporation heat is necessary for evaporation to occur. Also in this the energy is being used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point. So by using all these now we can answer this question.

Complete Step by Step Solution: Evaporation is the process by which water changes from a liquid to a gas or vapor. When the molecules of any liquid collide, they transfer energy to each other.
When evaporation occurs, the energy removed from the vaporized liquid should reduce the temperature of the liquid. This results in evaporative cooling.
Therefore, from the above options, the option that is not true is, D, as there is a difference between boiling and evaporation.

Therefore, the option D is not true about the evaporation.

Additional information: Evaporation is an important part of the water cycle. The heat from the Sun causes evaporation of water sources like oceans, lakes
There are some conditions for the evaporation of liquid.
For the molecules to evaporate, they must be located near the surface of the liquid and they must be traveling in the proper direction and they must have sufficient Kinetic energy
Evaporation also occurs in plants, it is known as transpiration.
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.

Note: There is a difference between boiling and evaporation. Simply put, boiling is the rapid vaporization of a liquid and evaporation is the process by which a liquid changes its state. We should not be confused between these two.
