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 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 C and State D. (d) Suppose there is another state of the system, State E, and that its energy relative to State A is
. Where would State E be on the diagram? [Section 5.2]
Problem 6EVisualizing ConceptsThe 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 E values, write two expressions for the difference in internal energybetween 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 its energy relative to State A isE = E1 + E4. Where would State E be on the diagram [Section]Solution 6EStep-1(a) Here we have to describe which of the states of the system has the greatest internal energy.From the above figure it has been found that the state A represent the ground state whereas stateB represent the excited state. It is known that the energy of excited state is greater than groundstate.Thus state B of the system has the greatest internal energy.\nStep-2(b) In terms of the E values, here we have to write two expressions for the difference in internalenergy between State A and State B.The change in energy or the energy difference between the state A and state B can be written asE ABThe energy expressions can be written as,E AB= E +1E or 2E AB = E +3E 4Step-3(c) Here we have to write an expression for the difference in energy between State C and StateD.The expression for the energy difference between C and D is given below,E CD = E 2 E or4E DC = E +3E 1Step-4(d) Here we have to describe the position of state E on the diagram depending on the given data,suppose there is another state of the system, State E, and its energy relative to State A is E =E1 E 4The energy of state E is found to be E + 1 wher4as the energy of state B is E + E . 1 2Since E > E , state E is above state B on the diagram. 4 2Hence state E would be the highest energy on the diagram.
