I donβt understand IM ON A TEST LOL (jk itβs convection losers)

radiation
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
example of conduction is heating a metal rod. the heat transmits without the movement of particles. convection is heating water. example of radiation is the heat received by sun. in this case, heat travels through vacuum WITHOUT heating the space between the sun and the Earth.
Depending on the scenario, it could be an example of all three, but the most common transfer of energy through heat associated with a heating iron would be conduction. If this is for school and it is possible to have more than one answer, then it would be conduction and radiation.
Conduction (through e.g. solid materials like metals that allow heat through - like a saucepan base) It is transformed into another object by touchConvection - in liquids and gases. Hot substances expand and so are less dense than cold substances. These less dense liquids and gases rise and cool ones fall forming a current. as an example, convector heaters in your home, the Gulf Stream that brings warm water from the Caribbean to Europe.Radiation - the method by which energy is transferred through a vacuum e.g. in the infra red heat energy from the sun as it travels across the vacuum of space.radiation, convection and conduction.
The fireplace's heat is an example of radiation.

Conduction, Convection and Radiation For example, for conduction you can use a boiling pot of water. For convection you can use a blender. For radiation you can use the sun or another one is your cell phone.
"C", radiation.

It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
The three methods of heat transfer are: (1) Conduction - particles bump into other particles, transferring energy. (2) Convection - moving masses carry heat with them. Especially, hot air (for example) tends to rise up, because of its lower density - the heat difference itself causes the currents. (3) Radiation. Objects radiate electromagnetic radiation, depending on their temperature. (The amount of energy radiated increases quickly at higher temperatures.)

the process whereby heat moves from one body or substance to another by radiation, conduction, convection, or a combination of these methods. Heat transfer flows from a body with high energy (higher temperature) to lower energy (lower temperature).
