State variable in thermodynamics
WebOct 17, 2024 · State variable: A Measurable macroscopic quantity that is only well defined, in the sense of describing the state of a system, if it is constant in time. And that is not subject to hysteresis. State function: A function between state variables, that are well defined and thus in equilibrium. WebThe first law of thermodynamics states that the change in internal energy of a system \Delta U ΔU equals the net heat transfer into the system Q Q, plus the net work done on the system W W. In equation form, the first law of …
