Delta U

Postby melissa_dis4K » Tue Feb 12, 2019 12:20 pm

I know that for a reversible, isothermic process delta U is zero because there is no change in temperature. Is delta U =zero for irreversible process as well? And if so, why? Thank you!

For irreversible processes, deltaU=q+w, so deltaU could be zero if q=-w. While it's possible, it's not ironclad like it is with reversible processes.
