Heat as relocated energy

Definition

Cooling is not the addition of cold but the relocation of heat, because heat is the internal energy of matter and cannot be scooped up or thrown away.

The chapter frames the entire cooling problem around this principle. Because heat is intangible internal energy, every cooling system works by moving heat from where it causes problems to where it can be rejected, rather than creating cold. This reframing motivates phase-change cooling, chillers, and cooling towers.
