Question:
Which equation is valid for adiabatic process?
Which equation is valid for adiabatic process?
Show Hint
Always remember two key adiabatic forms: \(pV^\gamma\) and \(TV^{\gamma-1}\).
Updated On: Apr 16, 2026
- \(TV^{\gamma-1} = \text{constant}\)
- \(pV^{\gamma} = \text{constant}\)
- \(T^{\gamma}V^{\gamma-1} = \text{constant}\)
- \(\frac{p^{1-\gamma}}{T^{\gamma}} = \text{constant}\)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
For adiabatic process:
\[
pV^\gamma = \text{constant}
\]
Step 1: Derived relation
Using ideal gas law: \[ TV^{\gamma-1} = \text{constant} \]
Step 2: Check options
• (A) correct form
• (B) also correct but not asked in required form
• (C) incorrect
• (D) incorrect representation
