isobaric
Same pressure throughout
Isobaric describes conditions of constant or equal pressure.
In meteorology, an isobaric line on a weather map connects points of equal atmospheric pressure.
In chemistry and physics, an isobaric process occurs at unchanging pressure: The gas expanded isobarically as it was heated.
The term appears in technical contexts involving pressure measurement or thermodynamics.
