Question

On a cold day, a metal front door knob X and a similar plastic knob Y are at the same
temperature.
Why does X feel cooler to the touch than Y?
A X convects thermal energy better
than Y.
B X is a better thermal conductor than Y.
C X is a better insulator than Y.
X is a better radiator of thermal energy than Y.​

Answer 1

Answer:

BX is a better thermal conductor than Y

Explanation:

Metal appears cool on touching because heat flows from body (at higher temperature) to iron (at lower temperature). This can happen only when metal conducts heat. Wooden surface does not feel cool as it is non-conductor of heat.
