Question

At a common temperature, a block of wood and a block of metal feel equally cool or hot. The temperatures of metal and wood are

(a) less than the temperature of the body

(b) equal to the temperature of the body

(c) greater than the temperature of the body

(d) either (a) or (c)

Answer 1

Correct option (b) equal to the temperature of the body

Explanation :

Since both the block of metal and the block of wood feel equally cold or hot, their temperatures must be equal to the temperature of the body. Otherwise there will be heat flow between the body and either of the blocks. And as the thermal conductivity of the metal is more than that of the wood, it would either feel more hot or more cold than that the block of wood.
