The diagram shows four states of a system, each with different internal energy, E.
(a) Which of the states of the system has the greatest internal energy?
(b) In terms of the ΔE values, write two expressions for the difference in internal energy between State A and State B.
(c) Write an expression for the difference in energy between State C and State D.
(d) Suppose there is another state of the system, State E, and that its energy relative to State A is ΔE = ΔE1 + ΔE4. Where would State E be onthe diagram?
