Assalamualaikum sir ap ne last diagram Jo Bnai hai equivalence wali us me ap ne heat engine ( nr ) = 100 % likha hua hai to is ka mtlb Kya hai (nr) ka or Qc ka Kya mtlb hai or Qh ka mtlb b btaden please

[@CID-dc7hf]

Thank you sir it's really helpfull Wishing u more success.

[@TalhasPhysicsAcademy]

Thank you so much.

Sir ye joo appne likhwayaa ha srf yhi Yaad Karna ha yaa phr Kuch aur BHI ?

[@sikumaheshwari7349]

Sir paper main equivalece main sirf yahi likhna hoga ky"if Kelvin statement proven wrong then clausis statement automatically will be proven wrong"?????

[@aestheticscents]

@talha physics academy. Sir apke lecture ko note karke isi me se yaad karsakhte hein?

Sir second law ne to ∆W= ∆Q + ∆U ko wrong sabit krdia kunke amount of work done plus change in internal energy amount of heat kay equal kese hoskti he agr aap ye keh rhe hen ke heat reject hoti he... To agr heat reject hui to workd done amount plus change in interbal energy to ∆Q nahi hoga na?

[@AhmedRaza-ft4ef]

Sir kia ye kelvin ki statement shi ha ? " It is impossible in a cyclical process to convert heat entirely into work, with no other change taking place .

[@TalhasPhysicsAcademy]

Equivalence of both statements hai.

[@skywalker8039]

Yes, right.

[@HashirAbdullahSiddiqui]

Sir i want to ask from you about the Equivalence of Kelvin-Clausius Statement that if we can use the work done of heat engine as a energy in Refrigerator? kindly explain it.

[@TalhasPhysicsAcademy]

Yes, this shows the failure of Kelvin statement will cause Clausius statement to fail.

[@HashirAbdullahSiddiqui]

@@TalhasPhysicsAcademy How Sir?

[@samarjan7159]

sir diagram ka pata nhi chal raha kelvin ki kon si hai or clausius ki kon si hai

[@TalhasPhysicsAcademy]

Wese dono ki alag hain but jo equivalence me hai wo to dono ko combine kiya hai.

[@waytocode]

Sir refrigerator mai Tu hot body k temp low hojata hai..agr cold body sai heat hot body ki traf move kry gi Tu hot body Ka temp or ziada brhna Chahiye..Jb k refrigerator Mai Hr cheez ka temp low hojata hai..?

[@TalhasPhysicsAcademy]

Cold body refrigerator ka ander ka compartment hai aur hot body bahar ka environment tb heat hamesha compartment se bahar ki taraf jati hai.

[@TalhasPhysicsAcademy]

Yes, likh sakte hain.

[@youmeandlove7390]

Sir,you explained good but I haven't understand the equivalence between them.Sir will you please explained it theortically.

[@TalhasPhysicsAcademy]

Equivalency means k dono statements ka mat lab ek he hai. Matlab ye hai k agar kal ko ek ideal heat engine bna liya jaye to ek ideal refrigerator bhi bnaya ja sakta hai jesa ki schematic diagram me dikhya gya hai.
