Question

Please describe the following.

1. Heat transfer
2. Conduction
3. Convection
4. Radiation
In your answer please put the number before the definition thank you.

Answer 1

Explanation: hope this helps

1. Heat transfer describes the flow of heat (thermal energy) due to temperature differences and the subsequent temperature distribution and changes.

2. Conduction describes the process by which heat energy is transmitted through collisions between neighbouring atoms or molecules. (Basically, it happens more readily in solids and liquids, where the particles are closer together)

3. Convection describes the process by which heat is transferred by the movement of a heated fluid such as air or water.

4. Radiation describes the energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it. It has wave-like properties so you could also call radiation “electromagnetic waves”.

Answer 2

Answer: These are the methods of energy transformation

Explanation:

• 1- Heat transfer :- it is the movement of heat from one substance or material to another. Heat transfer takes place through three principals- Conduction, Radiation, Convection.
• 2- Conduction :- it is the process by which heat energy is transmitted through collisions between neighboring atoms and molecules.
• 3- Convection :- it is the transfer of heat between two bodies by currents of moving gas or fluids.
• 4- Radiation :- it is energy that comes from source and travels through space at the speed of light.
