Differentiate between convection, conduction and radiation

Open in App

Solution

Convection
Conduction
Radiation
1.In conduction, heat transfer takes place between objects by direct contact. 1.In convection, the heat transfer takes within the fluid. 1.In radiation, heat transfer occurs through electromagnetic waves without involving particles.
2.The heat transfer takes place due to the difference in temperature. 2.The heat transfer occurs due to the difference in density. 2.The heat transfer occurs in all objects with a temperature greater than 0 K.
3.The heat transfer occurs through a heated solid object. 3.The heat transfer occurs through intermediate objects. For example, heat transfer between air and water. 3.The heat transfer occurs through electromagnetic waves.
