Question

Identify the mode of heat transfer.​

Answer 1

Three modes of transfer of heat:-

1. conduction

2. Radiation

3. convection

Answer 2

Answer:

In our everyday life, it has been observed that when a pan full of water is boiled on a flame, its temperature increases, but when the flame is turned off, it slowly cools down.

This is because of the phenomenon of heat transfer taking place between the pan full of water and the flame. It has been established that heat transfer takes place from hotter objects to colder objects.

When there are objects which are at different temperatures or there is an object at a different temperature from the surroundings, then the transfer of heat takes place so that the object and the surrounding, both reach an equilibrium temperature.

There are three modes of heat transfer.

1. Conduction
2. Convection
3. Radiation
