Matric part 1 Chemistry,Vapour Pressure - Ch 5r - 9th Class Chemistry

Topic 5.3 Liquid State".

- In this video follwoing sub topics have been taught:

5.3.2 Vapour Pressure

This lecture is specially recorded for students of 9th class, 9th class from all Punjab Boards and is based on the current curriculum of study for Chemistry book.

All these lectures are conducted in Urdu/English medium to facilitate Pakistani students.

SIZE OF MOLECULES; small sized molecules can easily evaporate than bigger molecules because they exert large vapourpressure . TEMPRATURE; the temprature is directly propotional to vapour pressure because when we increase the temprature the vapour pressure also increases due to increase in kinetic energy and then the process of evaporation starts and the molecules of water starts evaporating and with increase in temprature kinetic energy increses and we know that increase in kinatic energy will result as greater evaporation and grater vapour pressure

[drazharbarki]

when temperature increase the kinetic energy increase of liquid due to which intermolecular distance increases thus greater will be evaporation thus vapour pressure increases

U are a best teacher. U explain each and everything very clearly. From starting I have been taking your lessons. A good teacher is also blessing of Allah. You are blessing of Allah for me. ♥️♥️

[muhammadfiazawan]

in lockdown i will study easily thank you sir

[muhammadaslam]

I hate chemistry before your lectures but now I love chemistry🥰😄♥️

[zarekasif]

What a great lecture you've given.I'm understanding more from my school teacher.Thanks for giving such a good lecture

[duabismal]

i think, i am going to learn chemistry from this website next
time

[ahmadxdgaming]

as because of corona online studies are started but i am studying from here and i understand very well thanks for all this

Vapour pressure directly proportion to vapour pressure jitna t utna vapour

[creativecanvas]

Depends of vapour pressure
* Size of molecules:
Small sized molecules can easily evaporate than larger/ big sized molecules hence, small sized molecules of liquid exert more vapour pressure

* Temperature:
(Directly proportional)
At high temperature, vapour pressure is higher than at low temperature
For example :If we increase the temperature there will be high vapour pressure

[shakirasaeed]

Thanks for giving such a good knowledge

Or vapour pressure jab hamary sat ak container ho or us par cap ho mean ban container ho to him jitna ziada tempreture apply Katy ga to molecules upper container ka sat takrai ga vapis a kar surface pa pressure exert Kary ga to hamary pas vapour increase ho ga

Thankyou so much sir! This video helped me alot.

[sadiashahzadi]

Sir your methodology of teaching is wonderful, my points about vapour pressure is cleared

[UmairArshad]

I think your 1 of the best teacher in world

[ihsanullahshangla]

Sir, Your teaching method is very good .

[fidamuhammad]

Sir vapour pressure tempreture per asy depend ha ka ham jetna ziada tempreture da ga utny ziada vapour bany

AoA sir...from which book u teach us from?
