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

Answer» When we touch a steel rod and a PAPER simultaneously in winter, we feel the rod is comparatively COLDER because though the TEMPERATURE of both steel rod and paper are same, as steel being a good CONDUCTOR of heat, heat from our hand flows to steel but there is no transfer of heat from our hand to paper as it is a INSULATOR. So we don't feel cold when we touch a paper but we do when we touch a steel rod.
