The more general form of the first law of thermodynamics is $$\Delta U+\Delta (PE)+\Delta (KE)=Q-W$$ This includes the change in macroscopic potential energy of the system plus the change in macroscopic kinetic energy. So it takes into account the work-energy theorem. chivas vs pachuca horario
Thermodynamics - The second law of thermodynamics
WebFeb 20, 2024 · The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is. (15.1.1) Δ U = Q − W. Here Δ U is the change in internal energy U of the system. Q is the net heat transferred into ... WebThermodynamics Variables are either extensive or intensive. To illustrate the dif-ference between these kings of variables, think of mass and density. The mass of an object depends on the amount of material in the object, the density does not. Mass is an extensive variable, density is an intensive variable.
