Problem 6

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 $\Delta E$ 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 $\mathrm{C}$ and State D. (d) Suppose there is another state of the system, State E, and its energy relative to State A is $\Delta E=\Delta E_{1}+\Delta E_{4}$ . Where
would State $E$ be on the diagram? [ Section 5.2$]$

a)the state B of the system has greatest internal energy.
b) $$\begin{array}{l}{\Delta E=\Delta E_{1}+\Delta E_{2}} \\ {\Delta E=\Delta E_{3}+\Delta E_{4}}\end{array}$$
c) $\Delta E=\Delta E_{1}-\Delta E_{3}$
d) the state E will be placed above on the state
in the diagram.
