Question
On a cold morning, a metal surface on touching is felt colder than a wooden surface,because the metal has:
Options
A.low thermal conductivity
B.high thermal conductivity
C.high specific heat
D.low specific heat
Solution
Metal appears cool on touching because heat flows (at lower temperature). This canhappen only when metal conducts heat. Wooden surface does not feel cool as it is nonconductor of heat.
