internal energy change

[elliotyang]

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=C_v delta T is only for reversible process or both?

hi
i have a major problem.
plz help me.

how law of conservation of mass apply in nuclear reaction?
accoarding to laww input = output

plz tell me tha solution according to this law

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