    When we touch a steel rod and a sheet of paper simultaneously, why do we feel that the steel rod is colder than the sheet of paper?

    A)  Steel, being a good conductor, absorbs heat from our body.

    B)         Paper being a good conductor, absorbs more heat from our body.

    C)         Heat flows from steel to our body.

    D)         Heat flows from the paper to our body.

    Correct Answer: A

    Solution :

    Heat always flows from a hotter region to a colder one. Since, steel is a good conductor of heat, more heat will flow from our body into it and we will feel it as cold. As paper is a bad conductor, less heat will flow from our body.
