What is the difference between Conduction convection and radiation?

The transfer of heat by conduction requires a physical medium through which the heat travels. Convection involves transfer by the movement of air, and radiation requires neither a physical conductor, nor movement of a medium.
For example, if you place an iron Poker in the fire, eventually the end you are holding will get hot...this is conduction. When you turn on your car heater fan, the car eventually warms up through the movement of warm air...this is convection. When you stand in the sun, with 93 million miles of basically nothing between you and it, and still you get a sunburn, this is radiation.

∙ 8y agoConduction is the movement of energy by contact between two objects with differing amounts of energy. For example a hot rock placed into a pot of water will conduct energy to the water and raise its temperature, simply because the water is in physical contact with the rock.
Convention is the movement of energy from one place to another when the material containing the energy moves. For example, when air is heated by conduction from contact with the warm ground, the heated air rises and conducts that heat energy to places not in direct contact with the warm ground.
Radiation is the movement of energy on its own from one place to another. For example, a fire can radiate energy. If you stand to the side of a fire to avoid the conductive movement of heat through the air above the fire, you can still feel the heat from the fire on your skin. That is radiant heat.

∙ 8y agoAll these are types of heat transfer. Convection is when the rise and fall of warm and cool air or water makes a convection current. Conduction is when heat is transferred directly by one touching object to another. Radiation is when something (a hot object) gives off heat that can be felt. Radiation doesn't need atoms and molecules to work (meaning it can move through empty space) but the other two do.

What is the difference between conduction convection and thermal energy?
Conduction and convection are two ways in which thermal energy is transferred, the third way is by radiation.
How do you explain the difference between conduction convection or radiation can transfer heat explain?
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.
Why does the energy from the sun travel to Earth by radiation instead of by convection or conduction?
Convection and conduction require matter to travel through, and there is no matter between Earth and the Sun
What do conduction convection and radiation mean?
conduction is the transfer of heat between two surfaces in contact with each other convection is the transfer of heat into a moving fluid radiation is the transfer of heat via electromagnetic waves
What are 3 ways heat is produced?
Conduction, convection and radiation TRANSFER heat; you can't create heat; the law of conservation of energy states that energy cannot be created or destroyed. Therefore, you can't create heat.

What are the methods of heat transfer?
convection, conduction and radiation

What is the difference between conduction and convection a 5th grade answer please?
Conduction occurs in solids and liquids but not gases. Convection occurs in gases and liquids.
How is heat transferred between object or places?
One of three ways: conduction, convection, or radiation.
How radiation and convection is alike?
Conduction, Convection, and radiation are all ways that heat can be transferred between 2 objects. Conduction is transfer by direct contact like when you cook something on the stove. Convection occurs when heat is transferred by movement like in the Earth's mantle. Radiation occurs when waves are used to transfer heat like sunlight.
What are 3 ways heat is produced?
Conduction, convection and radiation TRANSFER heat; you can't create heat; the law of conservation of energy states that energy cannot be created or destroyed. Therefore, you can't create heat.
How heat naturally transferred between objects?
Heat can be transferred in three ways, which are called conduction, convection, and radiation.
How is earth atmosphere warmed evenly?
Energy is transferred between the earths surface and the atmosphere via conduction, convection, and radiation. Conduction is the process by which heat energy is transmitted through contact with neighboring molecules.
