Detailed Solution

Position P will be warmer.
Here, we can say that position P will be warmer because of the hot air rising. So, P corresponds to the convection, and T corresponds to the radiation. Convection transfers heat through the massive molecules that move in fluids like gases and liquids. The initial heat transmission between the item and the fluid occurs via conduction; however, the bulk heat transfer occurs owing to fluid motion. Radiation, on the other hand, can be defined as energy or particles from a source that flows through space or other mediums.
