Isochoric Processes: What's the Story?

[accidentprone]

I'm studying for my physics exam on thursday and an odd thought just struck me. It is easy to see where the names for isothermal and isobaric processes came from - iso being the latin for equal, thermal being to do with heat and baric being to do with pressure. However what about ischoric processes? All I can find online is that choric is to do with choirs? :s

 

[sophiecentaur]

I believe "iso" is from the Greek Isos.

hi accidentprone!

according to http://en.wikipedia.org/wiki/Isochoric_process#Etymology" …

The noun isochor and the adjective isochoric are derived from the Greek words ἴσος (isos) meaning "equal", and χώρα (chora) meaning "space." ​

Good Question

I found this at
http://encyclopedia.thefreedictionary.com/Isochoric+process

Etymology
The noun isochor and the adjective isochoric are derived from the Greek words ἴσος (isos) meaning "equal", and χώρα (chora) meaning "space."

So I guess that is somehow related to choir, with a stretch of imagination.

 

[sophiecentaur]

And Isotope means Same Place (in the periodic table).

Oh I see - it's Greek, not Latin. I should probably think in a wider context next time. Thanks for the help!

Indeed; from the Online Etymology Dictionary, Gk. khoros "band of dancers or singers, dance, dancing ground," perhaps from PIE *gher- "to grasp, enclose."
