उत्तर
A wooden knob and a metal latch are both being at the same temperature but it feels colder to touch the latch because the metal is a good conductor and as soon as we touch it heat from our hand flows to the latch and we feel cold while on the other hand wood is a bad conductor of heat, the heat of our hand does not flow into it, therefore, it does not feel cold.
