Question

Answer in one word.
1. The mode of transfer of heat from one particle
to another in solids.
2. The transfer of heat due to actual movement
of the heated particles within the medium.
3. The heat transfer from the source to a cold
object, without contact or medium between
them.​

Answer 1

Answer:

1. Convection

2. induction

3. radiation

Answer 2

Answer:

1. In solids, heat passes from one point to another through conduction. In Liquids and gases, heat transfer takes place by convection. Heat transfer takes place by the process of radiation when there are no particles of any kind which can move and transfer heat.

2. Convection is the process in which heat is transmitted from one place to other by the actual movement of heated particles. It is prominent in the case of liquids and gases..

3. Another good example of convection is in the atmosphere. The earth's surface is warmed by the sun, the warm air rises and cool air moves in. Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection.
