Is it radiation when put hands above fire.
You will feel radiant heat when you put your hands above a fire, which is heat transferred through electromagnetic radiation. This type of heat warms your hands by direct exposure to the fire's energy.
The heat you feel when you put your hands above a fire is primarily due to radiant heat transfer. This is the transfer of heat through electromagnetic waves emitted by the fire that heats up your skin. Additionally, convection currents created by the rising hot air from the fire also contribute to the heat you feel.
Radiation is the transfer of heat energy through electromagnetic waves. When you put your hands above a fire, the heat you feel is a result of the infrared radiation emitted by the fire, which directly warms your skin without the need for a medium like air to conduct the heat.
You can feel the heat from fire when sitting near it because heat is transferred through radiation, conduction, and convection. The infrared radiation from the fire warms your skin and surrounding air. This sensation is what makes you feel the heat.
No, rubbing your hands together will not set them on fire. Friction between your hands generates heat, but it is not enough to ignite them.

You can feel heat when you rub your hand together!

The friction generated by your hands creates heat.
No, you cannot light your hands on fire with friction alone. While friction can generate heat, it is not enough to ignite a fire on your hands. It is important to avoid attempting to create fire in this way as it can be dangerous.
The energy transfer from the fire to the person's hands is primarily thermal energy. Heat is being transferred through conduction from the warmer fire to the cooler hands, providing warmth to the hands.
An exothermic reaction would feel warm or hot if you put your hands near it, as it releases heat to its surroundings. An endothermic reaction would feel cool or cold if you put your hands near it, as it absorbs heat from its surroundings.
Heat has been transferred by conduction.
