Thermodynamics Class 11 notes Physics Chapter 12

WebA definite part of matter separated from whole of its amount and in which our attention is focused is called thermodynamics system. A system in which can exchange both energy and matter with its surrounding is called open system. The variable which is used to calculate a thermodynamic system completely is called thermodynamic variable. WebThe first law of thermodynamics is a formulation of the law of conservation of energy, adapted for thermodynamic processes.A simple formulation is: "The total energy in a system remains constant, although it may be converted from one form to another." Another common phrasing is that "energy can neither be created nor destroyed" (in a "closed system"). WebThe first law of thermodynamics is the application of the conservation of energy principle to heat and thermodynamic processes: The first law makes use of the key concepts of internal energy, heat, and system work. It is used extensively in the discussion of heat engines. The standard unit for all these quantities would be the joule, although ... ground ivy in lawn how to get rid of it
