Not really homework but..
This has been bugging me..
Let us venture into thermodynamics. Well the conceptual part.
What is an example of a system that does work, gives off heat and matter all at the same time.
(how about dN/dt, dQ/dt and dV/dt all being non zero?)
My dad suggested the sun because it is spinning, but I would like a more obvious example.
Was a previous exam question.
