Transcribed Image Text:1. Explain fundamental working mechanisms of conduction and convection modes of heat
transfer. What is the difference between thermal conductivity (k)- coefficient of
conduction heat transfer, and coefficient of convection (h) in convective heat transfer?
Expert Solution
Step 1
Conduction mode of heat transfer:
1.It is a type of heat transfer in which the molecule present in the body vibrates about their mean position.
2.This type of heat transfer can be from one body to another or within the body itself.
3.It mainly takes place in solid as there exists a strong intermolecular force between them.
Convection mode of heat transfer:
1.It is a type of heat transfer that basically occurs due to the flow of liquid or gases.
2.The heat transfer takes place in the direction where the flow of these gases or liquid takes place within the body.
