Assertion : All molecular motion ceases ...

Assertion : All molecular motion ceases at `-273^(@)C`.
Reason : Temperature `-273^(@)C` cannot be attained.

A

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

B

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

C

If assertion is true, but the reason is false.

D

If assertion is false but the reason is true

Text Solution

Verified by Experts

The correct Answer is:
C
When `T=-273^@C =-273+273=0K`
Hence, `c=0 as c=sqrt(T)`
All molecular stops. According to charles' law. The lowest attainable temperature is `-273.15^@C`.
