Isochore

The numerical results are given from which the authors deduce the relation for constant volume and additional reasons are given for believing acetic acid (whose vapour density at ordinary temperatures is abnormal) to be a mixture of C₂H₄O₂ and C₄H₈0₄, the former preponderating as the temperature rises. The authors ask the Society for a name to designate lines connecting pressure and temperature at constant volume, and for which they suggested “isochore”...

An isochore is a curve on a PVT diagram, the pressure and temperature being variable, the volume invariable.

Thus, an isochore transformation in this case is a transformation at constant volume.

1.3 shows the specific heat of argon measured along the critical isochore.

The isochore plan of the overburden thus obtained is then placed over the isochore plan of the seam.

Isochore maps of the sandstone bodies also indicate the presence of a number of channels flowing from the basin margin towards a central depression.

A model that accounts for the differential recognition of transgenes integrated at different chromosomal locations, is the isochore hypothesis.
