tilayhtälöön
Tilayhtälöön is a Finnish term that translates to "equation of state" in English. It is a fundamental concept in physics and chemistry that describes the relationship between various thermodynamic properties of a substance. Typically, an equation of state relates pressure, volume, and temperature, but it can also include other variables such as internal energy or entropy. The specific form of an equation of state depends on the substance and the conditions under which it is being considered.
For ideal gases, the simplest equation of state is the ideal gas law, PV = nRT, where P
Real gas equations of state, such as the van der Waals equation, account for intermolecular forces and
