WebThere are three types of systems in thermodynamics: open, closed, and isolated. An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air. A closed system, on the other hand, can exchange only energy with its surroundings, not matter. WebSep 26, 2011 · The key difference between enthalpy and entropy is that enthalpy is the heat transfer takes place in a constant pressure whereas entropy gives an idea of the randomness of a system. Moreover, enthalpy …
