If we touch a piece of steel and wood on a winter day we feel that the steel is colder than wood .if we touch the steel and the wood on summer day we feel that steel is hotter than wood why?

Explanation

On a winter day if we touch steel and wood, we feel that the steel is colder than wood because steel is a good conductor and wood is a bad conductor. Heat flows from our body to the steel surface is more or heat transfer rate is high. But the heat transfer rate from our body to wood is less, so, we feel that steel is colder than wood. When we touch steel and wood on a summer day, we feel that the steel is hotter than the wood due to the same reason. Here the rate of heat flow from steel to our body is more than the heat flow from wood to our body.
