Chemical Energetics
... Heat and work are best thought of as processes by which energy is exchanged, rather than as energy itself. That is, heat “exists” only when it is flowing, work “exists” only when it is being done. When two bodies are placed in thermal contact and energy flows from the warmer body to the cooler one, ...
