Verified by Experts

We know that steel is nuch better conductor of heat than wood. When we touch the steel chair, heat flows out from hand to the steel chair which in turn is conducted to other part of chair. So, more heat flows from our body to steel chair. Due to it, we feel cold.
When we touch the wooden chair, the heat flows from our body to the touched part of wooden chair but heat is not conducted to other part of chair. Hence , less amount of heat flows from our body to wooden chair. that is why, wooden chair does not appear cold.
