Question

At what common temperature would a block of wood and a block of metal feel equally cold or equally hot when touched?

Solution

When the temperature of an object is equal to the temperature of a human body, no heat is transferred from the object to the body and vice versa.
Therefore, the object appears equally cold or equally hot when touched.
