PhysicsMediumassertion reason
Assertion: A metal rod and a glass rod at room temperature feel cold when touched, while a cloth feels warm.
Reason: Metals and glass have a higher thermal conductivity than cloth, so they take heat from the hand faster.
Options:
Answer:
A
Solution:
Heat flows from the hand to a good conductor quickly, so the contact temperature falls and it feels cold. Cloth, a poor conductor, takes heat slowly. Both are true and the Reason explains the Assertion. A.
