When you touch a steel rod and a paper simultaneously you feel that the rod is comparatively colder why?

When you touch a steel rod and a piece of paper simultaneously, the rod feels colder because it conducts heat away from your skin more efficiently than paper does. Steel, being a metal, has a high thermal conductivity, allowing it to absorb heat quickly from your body. In contrast, paper is an insulator with lower thermal conductivity, so it does not draw heat away as effectively, making it feel warmer in comparison. This difference in heat transfer rates is why the steel rod feels colder to the touch.
