• D. P $\to $a, Q $\to $ c, R $\to $ d ,S $\to $ b

Answer 1

The Correct Option is A

To solve the question regarding thermodynamic processes, we need to match the processes given in Column 1 with their corresponding thermodynamic nature in Column 2.

Let's analyze each process type:

1. Adiabatic Process (a): In an adiabatic process, no heat is exchanged with the surroundings. The system is thermally isolated, and any change in internal energy is due to work done.
2. Isobaric Process (b): An isobaric process occurs at constant pressure. Pressure remains constant while volume and temperature may change.
3. Isochoric Process (c): This process occurs at constant volume, meaning no work is done since volume does not change.
4. Isothermal Process (d): Occurs at constant temperature. The internal energy remains constant, and any heat added is used for doing work.

Now let's match the types to the processes:

• Process I is characterized by No volume change, which matches with Isochoric (c).
• Process II shows No heat exchange, which matches with Adiabatic (a).
• Process III involves Temperature remains constant, matching with Isothermal (d).
• Process IV is characterized by Pressure remains constant, which matches with Isobaric (b).

Therefore, the correct matches are:

• P \to c
• Q \to a
• R \to d
• S \to b

This matches option: P \to c, Q \to a, R \to d, S \to b
