Convection

Definition

The transfer of energy carried along as matter itself moves from one place to another, with hot fluid physically carrying energy from higher temperature regions to lower temperature ones.

Convection demands coherence, meaning the medium must move as a connected whole and carry energy with it rather than shedding it along the way. Water’s cohesion holds the bulk fluid together so it moves as a coherent whole, enabling efficient convection. Fresh cold water sweeping past skin and carrying away surrendered heat is convection enabling further conduction.
