Assertion: Poisson ratio of atmospheric ...

Assertion: Poisson ratio of atmospheric gases is approximately equal to `1.4`.
Reason: Gases present in atomosphere are mainly diatomic.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Explanation is correct reason for statement `gamma=(C_(p))/(C_(v))=1.4`
for diatomic gases. Atmosphere mainly contains `N_(2) and O_(2)`.
