Question:
Which one of the following equations specifies an isobaric process? \([Q = \text{heat supplied}, \Delta P, \Delta V \text{ and } \Delta T \text{ are change in pressure, volume and temperature respectively}]\)
Which one of the following equations specifies an isobaric process? \([Q = \text{heat supplied}, \Delta P, \Delta V \text{ and } \Delta T \text{ are change in pressure, volume and temperature respectively}]\)
Show Hint
Prefixes: “iso” means same. “baric” refers to pressure (bar). So isobaric = same pressure.

- \( Q = 0 \)
- \( \Delta T = 0 \)
- \( \Delta V = 0 \)
- \( \Delta P = 0 \)

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
We need the condition that defines an isobaric process.
Step 2: Key Formula or Approach:
Isobaric means constant pressure.
Step 3: Detailed Explanation:
Constant pressure implies no change in pressure, i.e., \(\Delta P = 0\). \(Q=0\) is adiabatic, \(\Delta T=0\) is isothermal, \(\Delta V=0\) is isochoric.
Step 4: Final Answer:
Therefore, isobaric process is specified by \(\Delta P = 0\), option (D).
