Assertion : Woollen clothes keep the body warm in winter
Reason : Air is a bad conductor of heat.

A

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

B

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

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
It is know that Woollen fibres enclosed a large amount of air in them . The air is the bad conductor of heat and the coefficient of thermal conductivity is small. So, it prevent any loss of heat from our body body and keeps the body warm.
