Why is deltaU positive here? How do we know that U = Q - W must be positive?

Why is deltaU positive here? How do we know that U = Q - W must be positive? If the internal energy of a system increases as the result of an adiabatic on the system process, is work done on the system or by the system? Calculate the work done on or by the system in part (a) if its internal energy increases by 670 J. Adiabatic means that Q = 0 deltaU = Q-W> 0 why is deltaU greater than zero? delta u = 0-w>0 delta U > 0 means that - w> 0 so w is negative! w

Explanation / Answer

The question says that the internal energy of the system increases as a result of adiabatic process.

So, U = Ufinal - Uinitial > 0
