Pressure volume graph of two systems 'A' and 'B' are plotted under isothermal and adiabatic conditions. Which of the following observation of graph represents the two systems?
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Adiabatic expansion and compression are characterized by a more rapid change in pressure and volume. Isothermal expansion and compression are characterized by a slower change in pressure and volume compared to adiabatic processes. the specific path on the PV diagram depends on the particular conditions and constraints of the process. The key difference lies in the rate at which the changes in pressure and volume occur. The isothermal process has a more gradual change, while the adiabatic process has a more rapid change.

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.
