Answer
In control volume, when mass crosses the boundaries (inlet and outlet) of the control volume flow work is associated with it. Energy transferred by work can be in various form like mechanical, electrical, chemical etc. For example if turbine is taken as control volume then rotating shaft shall be considered as work energy.
