Exam Quiz 3, Physics 2C Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) Consider the equation Q= D U+W. Which of the following statements is WRONG? A) W is positive when the work is done on the system, and not by the system. B) If a system goes from state 1 to state 2 in a quasi-static process, the heat capacity depends on the path, whereas D U is independent of the path. C) When kinetic and potential energy (K and E p ) of the system change, the equation should be expanded as: Q = D U + W+ D K+ D E p D) To say that Q is positive in some process is the same as saying that the system obtains from the outside world a net positive amount of energy due to temperature difference alone. E) It applies to both reversible and irreversible processes. 2) Which of the following statements is WRONG? A) If a system goes from an equilibrium state 1 to an equilibrium state 2 in an irreversible way, the states 1 and 2 can still be described by points in a P-V diagram. B) If the volume expansion coefficient of mercury were lower than that of glass, one could build a functional
