उत्तर
In winter, an iron pillar feels colder than a wooden pole because iron is a good conductor of heat, while wood is a poor conductor.
When we touch the iron pillar, it quickly absorbs heat from our skin and transfers it away, making it feel colder. On the other hand, wood does not conduct heat efficiently, so it does not draw heat from our skin as quickly, making it feel relatively warmer.
