Enthalpy of a perfect gas

WebMay 6, 2024 · The law of perfect gas merely establishes the relationship between pressure, temperature, and volume. They are all proportional, and they act on gases at a constant … Enthalpy /ˈɛnθəlpi/ (listen), a property of a thermodynamic system, is the sum of the system's internal energy and the product of its pressure and volume. It is a state function used in many measurements in chemical, biological, and physical systems at a constant pressure, which is conveniently provided by the large ambient atmosphere. The pressure–volume term expresses the work required t…
