The first law of thermodynamics is a version of the law of conservation of energy, specialized for thermodynamical systems. It is usually formulated by stating that the change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings. The law of conservation of energy can be stated: The energy of an isolated system is constant.

Famous quotes containing the word law:
“The law is a sort of hocus-pocus science, that smiles in yer face while it picks yer pocket: and the glorious uncertainty of it is of more use to the professors than the justice of it.”
—Charles Macklin (1690–1797)
