• B. A-IV, B-II, C-III, D-I
• C. A-I, B-II, C-III, D-IV
• D. A-II, B-III, C-IV, D-I

Answer 1

The Correct Option is D

Step 1: Define Thermodynamic Processes

Isothermal Process

Characterized by constant temperature (\( \Delta T = 0 \)). The governing equation is:

$$ PV = \text{constant} $$

This process occurs at constant temperature (II).

Isochoric Process

Characterized by constant volume (\( \Delta V = 0 \)), resulting in zero work done:

$$ W = 0 $$

This process occurs at constant volume (III).

Isobaric Process

Characterized by constant pressure (\( \Delta P = 0 \)). The work done is calculated as:

$$ W = P \Delta V $$

This process occurs at constant pressure (IV).

Adiabatic Process

Characterized by no heat exchange (\( Q = 0 \)). The governing equation is:

$$ PV^\gamma = \text{constant} $$

This process involves no heat exchange (I).

Step 2: Match Processes to Conditions

• A-II: Isothermal → Constant temperature.
• B-III: Isochoric → Constant volume.
• C-IV: Isobaric → Constant pressure.
• D-I: Adiabatic → No heat exchange.

Step 3: Final Answer

The correct selection is: Option (4) A-II, B-III, C-IV, D-I.
