Question

Assertion :A piece of paper wrapped tightly around a wooden rod gets charred quickly when held over a flame compared to a piece of paper wrapped around a brass rod. Reason: Thermal conductivity of wood is smaller than the conductivity of brass

• A. Assertion is false and Reason is True
• B. Reason is false and assertion is True.
• C. Both Assertion and Reason are True and reason correctly explains assertion
• D. Both Assertion and Reason are True but assertion does not correctly explain reason

Answer 1

The correct option is C Both Assertion and Reason are True and reason correctly explains assertion

Statement 1 - True
Statement 2 - True and it correctly gives the reason
Piece of paper wrapped around a wooden rod gets charred quickly because wood is a bad conductor of heat and the paper reaches the ignition point easily whereas in the case of brass heat is carried away easily and paper cannot reach the ignition point quickly as in the case of wood.
