The three forms of heat are radiation, convection, and conduction. I see how radiation is different. But how are convection and conduction different? Conduction is heat transferred when things are touching. Convection is heat transferred via a gas or liquid---but isn't that just a special case of conduction, applied transitively (from a solid A to a gas/liquid B to a solid C)? It doesn't seem like it's genuinely something different.
- le-hu 5y agoBecause you are right - convection is just a special case of conduction https://physics.stackexchange.com/questions/497923/is-convection-just-a-variant-of-conduction-where-the-matter-is-circulating https://physics.stackexchange.com/questions/497923/is-convec...
- yesvee 5y agoConvection is with fluids. The molecules themselves move (not just transfer of energy). So different issues arise.
