Question

The value of $\gamma$ on monoatomic, diatomic and triatomic gases is ___, ___ and ___ respectively.

• A. 1.66, 1.40, 1.33
• B. 1.33, 1.40, 1.66
• C. 2, 1.66, 1.5
• D. None of these

Answer 1

The correct option is A 1.66, 1.40, 1.33

For now, it is a memory based question for you.
$\gamma$ = 1.66 [For monoatomic gases]
$\gamma$ = 1.40 [For diatomic gases]
$\gamma$ = 1.33 [For triatomic gases]
How to get these values?
We will deal with that in Physics

For now, just remember it.
