What is evaporation definition, examples & factors affecting evaporation|, rate of evaporation?

In this video, we will discuss 🔹What is evaporation?
In simple words, Evaporation is defined as a process by which water gets converted from a liquid form to a vapour form below the temperature at which it boils; in particular, the process by which liquid water enters the atmosphere as water vapour.
The rate of evaporation depends on the temperature difference between the evaporating surface and the air, the relative humidity, and wind & surface area.
🔹How does water evaporate?
Water molecules move faster when heat is applied. The faster they move the easier it is for them to escape. When that happens, evaporation takes place, explained with the help of 3d animated evaporation diagrams.
Evaporation process of oceans accounts for 80% of the water delivered as precipitation with balance occurring on land, inland waters and plants surfaces.
🔹How does the wind affect evaporation?
Wind can help evaporation continue when the maximum vapor pressure has been reached. The air in blowing wind moves around and expands, creating more room for the vapors.
Increase in surface area results in the increase of the rate of evaporation.
Increase in humidity decrease the rate of evaporation.
🔹Why evaporation causes cooling?
Evaporation causes the cooling effect as liquid surface molecules absorb heat & escape out in the form of gas or water vapors, resulting in the decrease the kinetic energy of remaining molecules & cause the cooling effect .
Examples of the cooling effect of evaporation are following:
- ether/Acetone drops place in a palm causes cooling palm.
- water in an earthen pot.
-the cold air of air cooler.
- sweating or perspiration in summer
- sprinkling water on floor or roof causes the cooling effect

Mam nice explanation and u hv cleared all of my dbouts, meaning, I don't even hv 1 dbout. So perfect and nice. Tq so much mam.

[DrFaheem]

You have spent a lot energy of presentation specifically on animation. Highly appreciated

[huangrichard]

I love how there a video for everything on youtube, nice

[banglafoodmania]

I think in the wind part, the wind not only creates space for water molecules but also transfer some of its kinetic energy the water molecules hence both factor enhances the evaporation process.

Tq tq tq so much don't stop making such amazing videos for students 💖💗💓💕

[sunitarawat]

Thank you so much mam... You are brilliant👍👍

[aniruddhabarde]

Very well explained I wanted a video which would explain each and every aspect of evaporation easily 😀 I found this video too helpful

[mahavirgupta]

this is very interesting video ....wow amazing concept thanks mam

[nishisharma]

very nice video and good and understandible explanation

[fszainyt]

I wish our teachers would be like this above one

[soumyakantibanerjee]

Requesting to make more videoes, on other the troupics of physical chemistry, like kinetics, colligative properties, phase equilibrium, solid state !--many many thanks 😊 🙏-also I requist for inorganic & organic also

[taeyeonmoon]

thank you so much miss. It was a fun yet helpful video! Please make more vids like these

[garrygill]

Mam tell diff btwn cohesion adhesion and gravitation

[ayushsarkar]

Mam, the spelling of chemistry is wrong!

[ig_itsaugi]

Understood everything in just 11 mind & then there was our chemistry teacher barking uselessly for an hour. 😂😂

[hizbullahkhan]

Mam plz cathode rays k bara ma videos upload kre plz

[SumitUpadhayay]

could you please explain evaporators also ?
thanks beforehand

[sanodiaellahi]

Can u plz explain how evaporation is independent upon amount of liquid
