Her er hvorfor:
* Stråling: Energy transfer through electromagnetic waves (like sunlight). While radiation can occur within fluids, it's not the primary mode of energy transfer.
* ledning: Energy transfer through direct contact between molecules. This is significant in fluids, especially at higher densities.
* konvektion: Energy transfer through the movement of the fluid itself. This is the dominant mode of energy transfer in fluids, especially when there are temperature differences.
Therefore, convection is the most common way energy is transferred in fluids, not radiation.
