- Ruby negiA to B is isothermal process(dT=0) so temperature is same.. B to C is isobaric process for dQ=nCpdT and C to A is isochroic process so dQ=nCvdT(dW=0)...Likes(0) Reply(0)

- Deepanshu ChaudharyIm not getting that how the ratio W/Q can be found?Likes(1) Reply(2)Abhishek singhwait a minute. I will give you exact method to do this question without Cv and Cp.

- Dhairya sharmadear bcoz it's reversible process and chnz in internal energy is o so work done will equal to heat absorbed. so efficiency of ideal reversible heat engine is one.Likes(0) Reply(3)Deepanshu ChaudharyBut the place where I saw this question, 1 was not in the option. The options were like 1/3, 1/6 , etc. I don't have the question right now.. I guess the engine is not reversible

- Abhishek singhyou can calculate the work done by area under the curve (area of triangle is 1/2* base * height.) and the heat intake can be calculated in isobaric and isochoric process. devide th...Show moreLikes(0) Reply(1)Deepanshu Chaudharyheat will be CvdT and CpdT. But we have not been given the atomicity of the gas used. so how can we calculate it?
- Dhairya sharmacarnot engine is reversible heat engine. we can calculate its efficiency . see the attachedLikes(0) Reply(2)Deepanshu ChaudharyI know this formula, but from the pv diagram how can we calculate?
