internal energy change
« on: September 11, 2009, 04:02:10 AM »
I got one doubt. Hope someone can clarify to me.
The internal energy change of ireversible process at constant temperature is equal as zero or not?
and the equation delta U=Cv delta T is only for reversible process or both?

as long as temperature is constant internal energy will be constant.so change will be zero.
yes delta u =cvdelta t for both processes.
