When air is blown with your lips closer, it is acting like a nozzle. When a fluid flows through a nozzle, velocity increases where as pressure and temperature decreases. When you keep your mouth wide open and blow, your internal heat is being rejected without being any pressure drop. Hence the temperature is warmer.
Sir these all process which we discussed are reversible or irreversible and as in isothermal temp is constant as it icreases and then decreases...so in same way heat content can also be not same first increasing and then decreasing?
sir in work done by adiabatic process u said equation is pv power gama is equal to constant and if we take pv equal to muRT then whole thing will change and so why dont we use muRT instead of taking as constant
sir if melting of ice is isothermal process so it internal energy also changes when it truns from ice to water while in isothermal process internal energy remains unchanged.
Sir, answer the question asked at the end of this video. The question is about blowing air on hand with mouth open and closed bring warm and cool sensation resp. How?
sir if we apply first law of thermodynamics in work done in isothermal process where change in internal energy is zero in this case Q=W this is contradiction of thermodynamics second law as this law does not allow tong convert all energy into work.sir i think i am wrong in thinking that in isothermal process change in internal energy is zero only temperature remains constant if i am right then please explain why change in internal energy is not zero provided temperature is constant.
Sir 0 degree pe ice ne state chng kei but temperature wahe 0 degree he hy tu state kesy chng huwa????I mean normally hum ice ko heat energy di kr he melt karty hy tu agr temperature constant hy tu phir hum ne kei kya? ???? Plz answer me
Hi..sir..ur videos are fantastic.. BT the classes students doesnot allow to listen carefully... Plzz put ur videos without students in classes(separately) ...
sir where is the heat gone in the adiabatic process.. and sir why we are doing a process adiabatically or what is the practical use of it.. please sir reply as soon as possible
Harshita Gaur heat is not gone anywhere since the wall is adiabatic I think u may b having a question when we down the pistol pressure increases hence temp increase yes it true the heat is stored in form on temp this energy can also be used to do work on pistol
sir mai aap ka seb video dekhta hu your all videos are really good your language are good sir please solutions chapter ka video benaye please please please please
superrrr awsome class . i feel like studing is so so much simple.honestly speaking .thank u sir

yes u r right
thnx bro, I was searching it, for ages....

sir you are outstanding teacher.....please keep motivate....always
i thank you sir from the bottom of my heart you have really taught me the essence of not only physics but also of leading a selfless life
Sir really aap se Accha physics koi nahi padha sakta h. Thanku so much sir for uploading these videos and making our concepts very much clear. 😊😊😊👍👍👍👍
sir you are doing great job
hats off to you
Sir,do we assume Cv as the specific heat of 1 mole of a gas at constant volume.
sir Iam from Nepal and studying science i watches your lectures and it helped me a lot.thanks sir.
sir in isochoric process if there is no change in volume then there should be no work done but we have the equation for work done in isochoric process
during ice formation the volume is increased by 9% its is suitable to consider it negligible?
100degree celcius water or 100degree celcius steam who would have greater heat capacity sir?
THANKS A LOT SIR .
THE WAY YOU TEACH IS SIMPLY AMAZING !!!
thx for uploading all the class 11 th video
Sir these all process which we discussed are reversible or irreversible and as in isothermal temp is constant as it icreases and then decreases...so in same way heat content can also be not same first increasing and then decreasing?
sir how volume changing by keeping pressure constant
sir in work done by adiabatic process u said equation is pv power gama is equal to constant and if we take pv equal to muRT then whole thing will change and so why dont we use muRT instead of taking as constant
Isnt Volume directly proportional to temperature? (Charles law)
How come temperature of gas increases when piston is pushed to decrease volume?
sir if melting of ice is isothermal process so it internal energy also changes when it truns from ice to water while in isothermal process internal energy remains unchanged.
Thank you so much sir for the quidance
plz help me frm where i get the chem videos.
a big thanx 4 u sir . you are really great
Sir, answer the question asked at the end of this video. The question is about blowing air on hand with mouth open and closed bring warm and cool sensation resp. How?
Sir in the textbook the equation for work done is given by 2.303nRT logV1/V2 as it was converted from ln. But sir you have only mentioned nRT logV1/V2
Sir plz tell me how volume changing by pressures constant
Respected sir please explain how you have written equation of Adiabatic process and what doe's gamma signifies here.
nice video......
Sir can you please suggest me questions of nccert book that are important for exam
Sir is evaporation of water isobaric or isochoric process?
sir here in adiabatic process u r saving pv^Y(GAMA)=CONSTANT AND U R WRITING pv^lamda=constant
Sir ye videos cbse k point of views se h ya iit/jee k
your videos are fab
sir if we apply first law of thermodynamics in work done in isothermal process where change in internal energy is zero in this case Q=W this is contradiction of thermodynamics second law as this law does not allow tong convert all energy into work.sir i think i am wrong in thinking that in isothermal process change in internal energy is zero only temperature remains constant if i am right then please explain why change in internal energy is not zero provided temperature is constant.
well done!!
sir, what is the answer of your last question?
Why gamma is mentioned in adiabatic process
sir mu is no of moles not molarity
pls recheck
molarity is property of a solution ..
Thank you very much sir !
Thanks sir m apke vedio dakh 12th m pas hua apka bhot bhot dhanywad
Sir 0 degree pe ice ne state chng kei but temperature wahe 0 degree he hy tu state kesy chng huwa????I mean normally hum ice ko heat energy di kr he melt karty hy tu agr temperature constant hy tu phir hum ne kei kya? ???? Plz answer me
Sir, i face problems in solving numericals. could you please tell me how can I help solving them?
Practice practice practice. First study concepts thouroughly, then start with easy problems, then gradually progress towards difficult numericals.
sir is not integration of 1/(v^gamma) ln (v^gamma) in calculating work done by adiabatic process??
+varun shah gamma is constant value
Yes buddy got it.
u r the best sir .......
tnxxx..
integration of (1/v)dv = log v (by definition)
sir please give the answer of that question which you asked in this video at last
Awesom
Hi..sir..ur videos are fantastic.. BT the classes students doesnot allow to listen carefully... Plzz put ur videos without students in classes(separately) ...
its really help me
sir aapne is video ke last me question puchha tha plz give answer i want to know
Sir thanks a lot you are amazing
in isothermal p1v1=p2v2 ?
please give the reversible and irreversible process defination
Sir... In last.. U said that work is done in isochoric process how is it possible if volume is constant
OK thanks I got it
it is useful us.
5:25 pressure is inversely proportional to volume ......toh agar gas expand hogi to pressure kaise constant rahega.....pls anybody tell me
amazing sir
sir may you explain me use mayeris process in real life
sir mic ka use kijiye plz
thank you very much sir...
Sir please aap pv diagram b btate or usme clock and anticlock wise jrur btate sir request hai pls
Ooosammm............
why are in efficieny multiply by 100 but in c.o.p not multiply by 100 c.o.p is also efficieny
Thank u so much sir
Sir thank you
Thank you, Sir
thank u Sir. ...u r God. .
thanks from Nepal
unique
Thanks sir .
yup! provided no. of moles remain constant.....
Ye gamma ko lambda kyo bana diya??
so nice
who is doing work and where in case of tyre releasing air due to a hole in it?
how is it isothermal ?
