A fixed mass of an ideal gas undergoes the changes represented by X --> Y --> Z --> X as shown below.
Correct answer: D. D
- A. A
- B. B
- C. C
- D. D
Explanation
During X--->Y, V↓,P↑During Y--->Z P∝1/VDuring Z--->X P=constant V↓

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
