With increase in the distance between the heat source and the object receiving the heat, the radiation heat transfer

ANS:A - decreases

As the distance between the heat source and the object receiving the heat increases, the radiation heat transfer: b) decreases This decrease occurs because the intensity of radiation decreases with distance according to the inverse square law. According to this law, the radiant energy received by a surface is inversely proportional to the square of the distance between the surface and the source. Therefore, as the distance increases, the radiant energy received by the object decreases, resulting in reduced radiation heat transfer.
