Final answer:
The type of heat transport experienced around a hot object varies by position; above the object involves convection, to the side includes radiation and some convection, below is mainly radiation, and touching the object results in conduction.
Step-by-step explanation:
When considering the heat transport experienced in various scenarios around a hot object, we analyze the modes of heat transfer: conduction, convection, and radiation.
Scenario Analyses
- Convection: Holding your hand approximately 12 inches above the hot object, you would mainly experience heat transfer through convection, as the hot air rises and transfers heat to your hand.
- Radiation and Convection: Holding your hand approximately 12 inches to the side of the hot object, you would experience heat transfer primarily through radiation, as the heat travels through the air to reach your hand, and partially through convection if air heated by the object circulates.
- Radiation: When holding your hand approximately 12 inches below the hot object, radiation would be the dominant mode of heat transfer, as heat radiates in all directions from the object.
- Conduction: By touching the hot object, you would experience heat transfer through conduction, as heat moves from the hot object directly into your skin.
Heat transfer occurs due to a temperature difference. When you are closer to the heat source or in direct contact, you feel the heat more intensely.
