Question

Assertion:- Immersion rod to heat water is made up of a metallic substance.

Reason:- Metals are good conductors of heat.

• A. Assertion:- True Reason:- False Reason is not the correct explanation of assertion.
• B. Assertion:- True Reason:- True Reason is the correct explanation of assertion.
• C. Assertion:- False Reason:- False
• D. Assertion:- False Reason:- True

Answer 1

The correct option is B

Assertion:- True

Reason:- True

Reason is the correct explanation of assertion.

Immersion rod to heat water is made up of a metallic substance because metals are good conductors of heat as they heat up faster when electricity is passed through them and process to heat water also become faster. Moreover, metals can withstand high amount of heat without melting. This makes metals as the preferred material to make immersion rods. Hence both the assertion and reason hold true and the reason is the correct explanation of assertion.
