underline and identify the parts of the text on this page that use examples of how the flow of the matter through a system is driven by energy and can do the work.

The parts of the text on the page that use examples of how the flow of matter through a system is energy driven and has the capacity to do work are;

1) The flow of water down rivers passing through hydro power dams to perform the following works;

2) The flow of electrons that corresponds to the flow of electricity (in the reverse direction) to perform the following works;

3) The lifting of the hammer by the cam which gains gravitational potential energy that is converted to kinetic energy as the hammer drops

The hammer is repeatedly lifted and dropped by the cam to do the following work

4) The chemical potential energy stored in bonds by virtue of the relative atomic distances which produces kinetic energy from the chemical potential energy
