Question

In the context of heat transfer, which statement accurately characterizes the process of convection?

Question 8 options:

Convection occurs only in fluids and is driven solely by temperature differences.

Convection relies on the direct collision of particles to transfer energy between regions.

Convection involves fluid motion resulting from temperature differences.

Convection is a process that only occurs in gasses and involves the emission of electromagnetic waves.

Answer 1

The statement that accurately characterizes the process of convection is:

Convection involves fluid motion resulting from temperature differences.

This correctly describes convection as a process that occurs in fluids (liquids and gases) where the movement of the fluid itself, driven by density differences caused by temperature variations, facilitates the transfer of heat.
