Note: Ice(s) -> Ice(l) => It's compression because ice in solid form has cage like structure and has more volume but in case of ice it's in the form of liquid. so, volume gets reduced. Thus, work done is considered to be positive.
@@sbqueen5741 the ice molecules have a cage like structure with vacant space between them in which air is trapped. this increases the volume of the ice, which in turn decreases its density. (You may have seen Ice floating in water).

Ans: Solid to Gas is expansion : W is done by the sys so -ve .. Thank you Thalaivaa.......❤
All the very best to all of you my dearest friends for the upcoming exam .never back down 💪
Pin pls ❤

But how?? The amount of water is increased and also the space occupied also increased then it could be a expansion

@@MARTIAN_07 Yes u are right made it wrong tnks for the explanation
@@MARTIAN_07thanks bro 👍🏻
But question is water in solid to water vapour 😅 so definitely volume increases therefore work done is -ve
Sir pls make more videos like theese, they are really helpful
Today is neet
💀
😢
🤡
Please make More Videos like This Daily Basis sir 😢😢😢
Ans.1- solid to gas- expansion
Work done by the system -ve
Ans.2- shortest wavelength in balmer series=2/R=1823.0A•
SQUARE KON KREGA
@@narutostories69 ayein?
Shortest wavelength for balmer=4/R
Pls continue like this sir
S sir
Really helpful tqsm sir❤
1- -ve
2- 3646 in case of hydrogen
Thank you sooo much sir......I am a big fan of you ❤❤❤
Sir please upload like this continuously sir its really useful for us💯
6:32 4/R
2:57 work done is negative
Lamda min for balmer series is 4/R
I m getting 2=R.lamda
W = - ve (expansion)
Solid contains no space .. and gases have much space and hence it undergoes expansioni.e work done is -ve
Ese legendry teacher mujhe pehle q nhi mile😢😢
Thank you ........
So muuch froom thee botttoom of heeeart......
Exppeectinng daily viideeos lliike thiss........
Do more videos like this sir
It is Very helpful to us
For balmer lemda min. Is 1/4R
Lamda min in case of balmer is 4/R
This series is very much helpful sir.. please continue and thanks a lot
Please do more such videos !!!! Please sir
Thank u sir amazing session. Pls do more such videos ❤
Very very helpful 😊😊❤❤❤❤😊❤😊
W=-ve Expansion (solid - gas)
4×10*-7m
Thank you so much sir..,plzz continue more videos like this sir..,
W=Negative bcx of Expansion
Thank you so so so so much. These short videos are very very useful 🌺💐
Continue this sir ❤❤
-negative work done sir
Thank you so much sir ♥️🫀🫶
Sir crystal field theory synopsis needed sir pls consider
Work should be negative
Work is negative in physics
Thank you sir❤ pls do more such videy
Thank you sir ❤❤🎉
Series limit in balmer is 3646Å
Sir your batch name please!?
sign of w ="-ve''; shortest lambda of balmar 3647 A
On 3 question value of w is( -ve) expansion
Thank you sir❤❤❤
listening to this and practicing questions can help me to get 120 marks? or should i listen to lectures?
1 q: w by system
Work expansion(-ve)
Thank you sir
Sir please do like this videos please
Solid to gas work is done by the system ie expansion so -ve
S to l expansion occurs so therefore work is done by the system and w= -ve
W=-ve sign
Tq sir❤❤❤❤
Thnk u❤❤
❤️
🔥🔥🔥❤❤❤
10 number ka bhee question nahi aya isme se 😆😆 likhne ko kuch bhee likh denge
❤
W=-ve
4*10-⁷m
Tmrw is neet
negative work
Sir kindly do the same for organic chemistry reactions pls
Lamda min is 4 /R
W = - ve
20 marks sure??
Sir please stop fooling students
Work is negative
Thanks alot sir this series is helping a lot sir 🙏
Tq so much sir
Tq sir❤
❤❤❤❤
❤
W = -ve
