Sign conventions for heat and work
WebMay 22, 2024 · In thermodynamics, work performed by a system is the energy transferred by the system to its surroundings. Kinetic energy, potential energy and internal energy are forms of energy that are properties of a system. Work is a form of energy, but it is energy in transit. A system contains no work, work is a process done by or on a system. Webem Green * House tSTAURANT, nd 14 Sooth Pratt Strwt, •« W«t .r M»ltb, BMW.) BALTIMORE, MO. o Roox FOR LADIES.
