Question

Convection heat transfer mode is comprised of which of the following mechanism? Select one: O a. Energy transfer solely due to macroscopic motion of fluid O b. Energy transfer solely due to microscopic motion of fluid o c. Energy transfer solely due to diffusional motion of fluid O d. Energy transfer due to macroscopic and diffusional motion of fluid

Answer 1

Option c.

Step-by-step explanation:

Convection - transfer of heat mode is that technique of transfer of heat in which heat and thermal energy can be transferred from one point to another point in the system by the random movement of the molecules of the fluid. This method of transfer of heat or the mechanism of transfer of heat by convection is the most dominant form of transfer of heat in gases and liquids.

Therefore, we can say that convection involves the transfer of heat as a result of the macroscopic and some random movement of the fluid molecules.
