Just had a thermodynamics exam, and one of the questions was(adsbygoogle = window.adsbygoogle || []).push({});

For an ideal gas, is the relation [tex]\Delta[/tex]U = mC[tex]_{}v[/tex][tex]\Delta[/tex]T restricted to constant volume processes only? Why?

I wrote that it was only valid for constant volume processes, because this is what C[tex]_{}V[/tex] is defined as, however now i'm starting to think that is only true for Q, and that equation is true for any process, not just constant volume.

thanks in advance!
