Temperature is a state function
Web2 Nov 2015 · Essentially, the first law of thermodynamics tells us that there exist a state function called internal energy, U, the increase in which for a closed system during a thermodynamic process is equal to the heat supplied to the system plus the work done on the system, Δ U = q + w, or in infinitesimals for a quasistatic process, đ đ d U = đ q + đ w. Web8 Mar 2024 · The value of state function remains the same regardless of the number of steps. The value of path function of a single step process is different from a multiple step process. State functions include entropy, …
