Question

From the figure shown for a thermodynamic system, match the curves with their respective thermodynamic processes (P - Pressure and V - Volume)

Curve | Process I | a) Adiabatic
II | b) Isobaric
III | c) Isochoric
IV | d) Isothermal

• A. I-c, II-a, III-d, IV-b
• B. I-c, II-d, III-b, IV-a
• C. I-d, II-b, III-a, IV-c
• D. I-a, II-c, III-d, IV-b

Hint:

Remember: - Isochoric: constant volume, vertical line on PV graph. - Isobaric: constant pressure, horizontal line. - Isothermal: constant temperature, hyperbolic curve. - Adiabatic: no heat exchange, steeper curve than isothermal.

Answer 1

The Correct Option is A

Step 1: Identify curves from the PV diagram
- Curve I: Vertical line, volume constant → Isochoric (c) process.
- Curve II: Sloped curve without heat exchange → Adiabatic (a) process.
- Curve III: Curve at constant temperature → Isothermal (d) process.
- Curve IV: Horizontal line, pressure constant → Isobaric (b) process.
Step 2: Match curves with processes
Thus, matches are: I-c, II-a, III-d, IV-b.
