Work (thermodynamics) of the energy went out as heat, and how much as work. This can be summarized by saying that heat and work are not state functions of the system. This is in contrast to classical mechanics, where net work exerted by a particle is a state function. Pressure–volume work (or "PV" work) occurs when the volume of a system changes. "PV" work is often measured in units of litre-atmospheres where = . However, the litre-atmosphere is not a recognised unit in the SI system of units, which measures P in Pascal (Pa), V in m, and PV in Joule (J),
Dictionary of Scientific Biography become the standard against which to measure all multi-volume biographical works in history of science." Dictionary of Scientific Biography The Dictionary of Scientific Biography is a scholarly reference work that was published from 1970 through 1980. It is supplemented by the New Dictionary of Scientific Biography. Both these publications are comprised in an electronic version, called the Complete Dictionary of Scientific Biography. The "Dictionary of Scientific Biography" is a scholarly English-language reference work consisting of biographies of scientists from antiquity to modern times, but excluding scientists who were alive when the "Dictionary" was first published. It includes scientists who worked
