Process

===Thermodynamics===
*[[Process function]], a mathematical concept used in thermodynamics
*[[Thermodynamic process]], the energetic evolution of a thermodynamic system
**[[Adiabatic process]], which proceeds without transfer of heat or matter between a system and its surroundings
**[[Isenthalpic process]], in which enthalpy stays constant
**[[Isobaric process]], in which the pressure stays constant
**[[Isochoric process]], in which volume stays constant
**[[Isothermal process]], in which temperature stays constant
**[[Polytropic process]], which obeys the equation <math>p v^{\,n} = C</math>
**[[Quasistatic process]], which occurs infinitely slowly, as an approximation
