Exam Quiz 3, Physics 2Ca Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) Consider the equation Q = ΔU + W. Which of the following statements is WRONG? A) W is positive when the work is done by the system, and not on the system. B) If a systems goes from state 1 to state 2 in a quasi - static process, the heat capacity depends on the path, whereas ΔU 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 = ΔU + W + ΔK + ΔE p D) To say that Q is positive in some process is the same as saying that the system transfers to the the outside world a net positive amount of energy due to temperature difference alone. 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 cannot be described by points in a T - V diagram. B) If the the volume expansion coefficient of mercury were lower than that of glass, one could build a
