WebEnergy is measured in terms of its ability to perform work or to transfer heat. Mechanical work is done when a force f displaces an object by a distance d: (1) w = f × d. The basic unit of energy is the joule. One joule is the amount of work done when a force of 1 newton acts over a distance of 1 m; thus 1 J = 1 N-m. Web1) In a transfer of energy as heat without work being done, there are changes of entropy in both the surroundings which lose heat and the system which gains it. The increase, Δ S , of entropy in the system may be considered to consist of two parts, an increment, Δ S ′ that matches, or 'compensates', the change, −Δ S ′ , of entropy in the surroundings, and a …
