coefficient de dilatation isobare

English translation: isobaric expansion (coefficient)

GLOSSARY ENTRY (DERIVED FROM QUESTION BELOW)

Science - Science (general) / Thermodynamics
French term or phrase: coefficient de dilatation isobare
In text talking about thermodynamics:

"Mon calcul pour trouver une valeur au coefficient de dilatation isobare est juste !"
"Votre résultat m’a l’air juste, mais votre calcul est faux !"

Also, stupid question, would you say "calculations" here for "calcul"?

isobaric expansion (coefficient)
Explanation:
"dilatation isobare" is "isobaric expansion". (For some explanation, see, eg page 2 of http://physics.usask.ca/~plyukhin/ep271/assignments/sol9.pdf...
The term coefficient can be added to this compound - but isobaric expansion coefficient is rarely used. As explained in the pdf file above, the isobaric expansion follows the very simple law
T/V (temperature divided by volume) = constant, so if you need to know the final volume, V_f, you get it by V_i x (T_f/T_i), where the subscripts refer to f(inal) and i(initial). T_f/T_i is just the ratio of the two temperatures, measured in Kelvins. If temperature is measured on the Fahrenheit or the Celisus scale, the formula is a bit more complicated - and in that case isobaric expansion coefficient makes sense.

I would use "calculation" (in singular) for "calcul", since it is just derivation leading to a result.

Great! Thanks

agree  SusanMurray: I'd put "isobaric expansion" without coefficient like Attila. For info, thermodynamic temperatures expressed in Kelvins are described as absolute temperatures. Ref: Thermodynamic Tables in SI Units.

5 not 3 for confidence. But anyway, I see Attila beat me to it with a good answer.
