What are the similarities and differences between conduction and convection?
Answers
Explanation:
In convection, the heat transfer takes within the fluid. In radiation, heat transfer occurs through electromagnetic waves without involving particles.
The heat transfer takes place due to the difference in temperature. The heat transfer occurs due to the difference in density. The heat transfer occurs in all objects with a temperature greater than 0 K.
The heat transfer in conduction is slow The heat transfer in convection is faster. The heat transfer in radiation is the fastest.
The heat transfer occurs through a heated solid object. The heat transfer occurs through intermediate objects. For example, heat transfer between air and water. The heat transfer occurs through electromagnetic waves.
It does not follow the law of reflection and refraction. It does not follow the law of reflection and refraction. It follows the law of reflection and refraction.
Answer:
Similarities :-
Conduction is the transfer of heat by direct contact; Convection is the movement of heat by actual motion of matter.
Differences :-
Conduction: It transfers heat and requires a solid .
Convection: It transfers of a heat in a fluid can be liquid or a gas .
