Question
If the body temperature is raised from 20 K to 30 K through physical contact, then it is called as _______
- Conduction
- Convection
- Radiation
- None
Hint:
Heat transfer occurs through conduction when the two bodies are in contact
The correct answer is: Conduction
- Conduction is the method of heat transfer in which the heat flows from the hotter part to the colder part within the same body or different bodies.
- Conduction takes place when the bodies are in contact.
- In conduction, the particles take up the energy and vibrate at their mean position and transfer the energy to the adjacent particles.
- Hence the temperature of the body is increased by the process of conduction when the two bodies are in contact .
