Question
Sand on the sea is hot when touched, the heat transferred is ______
- Conduction
- Radiation
- Convection
- None
Hint:
Conduction is the method of heat transfer when the two surfaces are in contact.
The correct answer is: Conduction
- Conduction is the method of heat transfer from the hotter part to colder part within the same body or different bodies.
- When the hot sand is touched there is the temperature difference between our body and the sand .
- our body is cold when compared to hot sand .
- So there is flow of heat from the sand to our body when the hot sand is touched due to temperature difference.
- Since our body is in contact of the sand , heat transfer is by the process of conduction.
