[@souravdey799]

Sir , wifistudy is very helpful .. thanks .. thumps up ur initiative.

[@SanjayPrajapati-on5jh]

Sir ap bhaut achhe se smjh te ho ,or apki vhja se hum khai se bhi kuch bhi sikh skte thank you WiFi study channel 🙏🙏🙏

[@danishiqbal6006]

Thanku sir....Really it is called "Changing the way of learning"

[@raorajesh9582]

Best Explained sir 👍

[@kshitijpandey7487]

At 1:06:00 you told two points 1-Every quasi static process is reversible. 2-Quasi static with friction is irreversible. My question is then how every quasi static is reversible if it(with friction) is irreversible? So accordingly, It should have been stated as quasi static process without friction or any other external force (due to which the system and surroundings are undergoing any net change in work or heat individually) is reversible. Please is doubt ko clear kare sir.

[@kshitijpandey7487]

I am sorry maine aage ka part dekha nahi jisme aapne apni galti maante hue is doubt ko clear kiya hai

[@Carnot709]

Sir you are the best.....too good sir

[@pritamdeb5892]

Thank u sir..... Bohat a6a laga

[@Pankajkumar-oq5bs]

Thank you very much sir .......aapne study easy kar diye.

[@ParasKumar-oj4lc]

Your way of teaching is very amazing

[@amrityadav8462]

Sir, aapke samjhane ka tarika etna best h ki mai kya kahu aap sare topics ekdm achhe se cover kr dete h👌👌👌👌👌

[@Suriya7889]

The pressure and specific volume of the atmosphere are related according to equation PV = 2.5 × 10^5 where p is N/m2 and v is m3/kg. What depth of atnosphere is required to produce a pressure of 1.033 bar at earth's surface? Assume g= 9.81 m/s2

[@DhirajKumar-Learnwithfun]

Your teaching experience is awesome

[@sadanandathongam5915]

Chmecal equibrium means rate of forward reaction equal to rate of backward reaction, it is not chemical inactive I think... cz even in the equilibrium state still reactant to product , product to reactant goes on...but both forward and backward rate are same..

[@techknow1542]

Here we talking abt chem equilibrium at macroscopic lavel not microscopic lavel and atomic structure lavel

[@himanshunautiyal1052]

Thats not correct @Techknow!!! See! Of course chemical reaction isn't inactive... who says it is. but we consider this necessary for the condition of thermal equilibrium. E.g. if in a exothermic equilibrium reaction, the reaction is reversed it becomes endothermic equilibrium. Like decomposition of NH3 into N2 and H2.

[@PAPPUKUMAR-us7yt]

Love ur effort sir , bhut mehnt karta hoo AAP lecture k liya

[@siadeep]

Sir I have 2 questions. 1. In PV diagram why we take y axis as P and x axis as V ? 2. Why Area under the curve in PV diagram is workdone by system ? Please sir explain these two points. Thank you

[@arunpatel5643]

1. y=mx+c. we get value of y only when we vary value of x. y is dependent on x. same way pressure is dependent on volume. same with stress strain diagram. you get stress only when there is strain available because stress is dependent on strain. Can you produce STRESS without any FORCE....? 2. work done is P.dV . same as area of rectangle , length = P(constant) X breadth =dV= (v2-v1).

Bahut khub sir....

[@ArunKumar-gs5mn]

Very very thanks sir ji

[@ramakantrao896]

Great lecture sir ji

[@011cutebaby]

@1:15:30 Volume is not intensive property???? So how it is taken as DOF??

[@atulgupta2152]

Pleaase sir ..upload more videos...related to ssc je mech thanku

[@ckytalk8005]

You are really great sir

[@gopalkrishnatiwari8070]

[@manzoorbakshiofficial5448]

I am speechless how to thank you n your entire team sir !!!!!Thank you so much sir!!!!!

[@amaanliyaqat6569]

Sir you r great..!!

sir you are doing a great job. Thanks a lot.

[@himanshujasaiwal3967]

But ab to classes band hogi na bhai 😐😐😐😐

[@ruraldevelopment8141]

God bless you always happy

[@prakashchhatria6573]

15:40 mai aap bole ki 1-2 mai system kuch na kuch heat release ki toh 2-1 mai kyun heat nahin release ki...karna chahiye na?

[@studywithparas1127]

Process ko final position pr phuchane ke liye heat deni padgi na ki release krni padni

[@mdadnankne9214]

The way of teaching is 👌👌❣️❣️❣️

[@rahulsinghbhati5002]

All Quasi-Static process is Reversible process but all Reversible process are not Quasi-Static process.

[@RAHULKUMAR-qe8kl]

Yes

[@emmycreations2236]

good job sir

[@AjaySolankiBKN]

Sir every reversible process is not quasi static? Esko thoda example k sath explain krdo..

[@himanshunautiyal1052]

Mr. Neeraj! I request you to clear my one doubt. You said that all reversible processes are quasi-static and quasi-static processes are extreamly slow. But in almost all cycles we use reversible processes only which of-course will be extremely slow.. but that is not they are. Please help.

[@AnujKumar-rp9yy]

Sir molliaer diagram par ak vidieo banayega please because ssc je me har shift me pucha gaya tha

[@ashishgoel8059]

You're too good

[@ruraldevelopment8141]

Very nice sir

[@shubhamdeshmukh6339]

Sir chemical engineering bhi pdaiye na Please..... please....

[@mskInspire]

Mast sir

[@SanjayPrajapati-on5jh]

Sir ap gate ke bhi ek do question solve kr va diya kro or kis type ke question aa skte h vo bhi pls....

[@PrashantKumar-ph9xt]

Looking smart

[@ashwanirathore5818]

a quasi static with friction is what??

[@KaranKumar-ge3gn]

Irreversible process

[@moharsingh4867]

Sir water at 100 degree Celsius and steam at 100 degree Celsius..kya thermodyamic equilibrium mai hai

[@techknow1542]

They are in thermal equilibrium but may be or may be notin Thermodynamic Equilibrium

[@PAPPUKUMAR-us7yt]

Nai hai .....because until temp remains constant but it's heat get utilities in for kinetic for to convert water molecules into vapour............reason ahi ha baki sir sa kya bolta hai dekho

[@PAPPUKUMAR-us7yt]

So , agar kinetic ki baat aaya to woh thermodynamics k equilibrium Ko follow nai karega

[@H2ORevives]

❤️❤️❤️❤️sir

[@sulendrasontirkey1074]

Sir, all mechanical device is open system then piston cylinder also should be open system but generally piston cylinder is an example of closed system why ?

[@himanshunautiyal1052]

The example PISTON CYLINDER ARRANGEMENT WITH VALVES CLOSED is type of closed system. Not considering the valves condition, it is open.

[@Kumar-zt5de]

Sir aap aacha padhate ho muje apke sare lecture nhi mil ree h muje link dijiye ya aage ka video upload nhi h to please kr dijiye thermodynamics iske aage ka lecture 42 please sir

[@vanshdixit5705]

sir ye videos syllabus m hai kya heat engine

[@saurabhtanwarfitness]

Sir Wo ssc je ka 12 saal pehle ka level h current ssc je ka level bahut high h

[@techknow1542]

No sir you r wrong there are some more reason any kinds of dissipative effect fastness of process for a irreversible process

[@anjanichaudhary1363]

Nice video

[@Suraj.Singh123]

Iski pdf kha se milegi??

[@satyampandey2728]

Sr frictn ek irreversibl process kaise h...kl ek br short m btaega sr....plzzz

[@techknow1542]

Bcz of when you repeat same orocess in opposite ditection so you will not get same amt of heat or work or mass means there are some losses in energy or mass you can whatsap me 7985299503

[@himanshunautiyal1052]

See Shubham!! I try to clear your doubt. Reversible process is one which doesn't leave any residue behind. Let us consider piston cylinder arrangement. If piston slides from A to B due to gas pressure or any other means friction cause heat to generate. Now, again bringing it back at A, piston slides again and generates heat again... so though you have bring the system at initial state but net heat transfer( or heat produced) is not zero.... This is why friction causes irreversibility .

[@spikylove1630]

[@ashwanirathore5818]

what is the DOF for liguid+ solid in case of water

[@RAVIRAJ-kn2hg]

Dof=1

[@ajayraut-xl3zg]

Specific heat intensive h ya extensive ???

[@abhishek4219]

Intensive

[@dhruvchampaneri2279]

If specific term is come all the process are intensive
