Question

DEFINE EVAPORATION.. ​

Answer 1

Answer:

On average, only a fraction of the molecules in a liquid have enough heat energy to escape from the liquid. The evaporation will continue until an equilibrium is reached when the evaporation of the liquid is equal to its condensation. In an enclosed environment, a liquid will evaporate until the surrounding air is saturated.

Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water. In hydrology, evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration. Evaporation of water occurs when the surface of the liquid is exposed, allowing molecules to escape and form water vapor; this vapor can then rise up and form clouds. With sufficient energy, the liquid will turn into vapor.Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other

✦ Question ✦

What is evaporation ?

$\Large{\underline{\underline{\bf{Answer:-}}}}$

• The process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils.

• In easy way , the process by which liquid water enters the atmosphere as water vapour.

❥ Examples of Evaporation ❥

• Evaporation of acetone which is used for removing nail paint is another everyday example of evaporation.

• The melting of an ice cube is an example of evaporation.

• Drying Clothes under The Sun.

• Ironing of Clothes.

• Preparation of Common Salt
