If w1 w2 w3 r the works done in isothermal , adiabatic , & isobaric processes , the correct order will be , if Î”V is same for all the processes

(A) w1 > w2 > w3

(B) w3 > w2 > w1

(D) w3 > w1 > w2

hori line - isobaric
middle line - isothermal
bottom line - adiabatic

so, w3>w1>w2

Ya Asish that way ya ure right

But c this is my confusion :

In isobaric w = pÎ”V

In adiabatic w = pÎ”V/ Î³-1 > w due to isobaric ????

@uttara: the mistake ur doing is this

In adiabatic w = pÎ”V/ Î³-1 > w due to isobaric ????

the bolded portion is wrong

W(adia) = Î”(PV)/(Î³-1)
Î”(PV) â‰ P(Î”V)

so ull have to go by other means

Ohhhh Yaaaa

So sorry

Got my mistake
Asish

Thanks :)
