Thermodynamics

A constant-pressure process

In thermodynamics, an isobaric process is one that takes place at constant pressure, so that as a system is heated it expands and does work on its surroundings while its pressure stays fixed (the familiar case of a gas warming under a free-moving piston or at open-atmosphere conditions). On a pressure–volume diagram an isobar is a horizontal line, and the heat added relates to the change in enthalpy. Çengel and Boles's Thermodynamics: An engineering approach treats the constant-pressure process among the basic idealised paths. The referent is a constant-pressure thermodynamic path, and it is unrelated to a nuclear mass-number family or a weather-map contour apart from the equal-pressure root.[1]

Unit
A thermodynamic path along which pressure is held constant

Not applicable
Measured by
Represented as a constant-pressure path on a P–V or T–s diagram; heat exchanged equals the enthalpy change
