Question

$\huge 50 \: points$
n moles of a monoatomic gas undergoes a cyclic process as shown in the figure, find efficiency​

Answer 1

first calculate work done(W.D)

W.D=(Note that work done will be zero in case for the part AB and CD they are isochoric process)

therefore,W.D will be due to AD and BC and these are isothermal process so the work done will be equal to =uRT ln(V2/V1) where u is no of moles.

after that to calculate the amount of heat supplied use uCvdt for isochoric and uCpdt for isobaric proceeds(take proper signs)

After calculation of both work done and heat supplied

Efficiency=Work done/heat supplied

Hope it helps :))

Answer 2

Explanation:

Efficiency = work done /heat supplied

So,

Efficiency =31%
