Are the following statements true or false? (1) CV and CP are always constant for ideal gases. (2) CV is always smaller than CP for any ideal gas. (3) For a closed system at a given state in the absence of external fields, U =Q+W. (4) U remains constant in every isothermal process in a closed system. (5) W = 0 for every cyclic process. (6) U = 0 for every cyclic process. (7) If neither heat nor matter can enter or leave a system, that system is an isolated system. (8) For a closed system with P-V work only, a constant-pressure process that has Q > 0 must result in an increase in temperature of the system. (9) The value of U is independent of the path (process) used to go from state 1 to state 2. (10) If the final temperature of a system equals its initial temperature, the system must have undergone an isothermal process. (11) The second law of thermodynamics is based on conservation of entropy. (12) The entropy of a closed system can never decrease. (13) When a substance is in its standard thermodynamic state, the substance must be at 25C. (14) The chemical potential
