Advection

By transferring matter, energy—including thermal energy—is moved by the physical transfer of a hot or cold object from one place to another. This can be as simple as placing hot water in a bottle and heating a bed, or the movement of an iceberg in changing ocean currents. A practical example is thermal hydraulics. This can be described by the formula: ϕ q = v ρ c p Δ T {\displaystyle \phi _{q}=v\rho c_{p}\Delta T} where
