Question

Conduction of heat and covection(Give two points of difference between the following)​

Answer 1

Answer:

Convection Radiation

In conduction, heat transfer takes place between objects by direct contact. 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 0K.

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
