Unformatted text preview: The addition of work, however, can't change the entropy of the system since we are only changing the external environment of the system. We can look at the thermodynamic identity in a new way. The first term, τ dσ , can be thought of as the heat input, written dQ . The second term,  p dV , can be thought of as the work input, written dW . The third term, μ dN , can be thought of as the chemical work input, written dW c . Therefore the total change in energy is due entirely to the sum of the heat inputted, work, and chemical work done on the system....
