     An ideal gas undergoes a polytropic process pV^n = constant with n = 1, this process must be:  an adiabatic process  an isothermal process  a reversible process  an isometric process  Among the four statements below, the incorrect one is:  the change of a property during a process depends only on the initial and final states of the process;  the change of a non-property during a process depends on the particular process itself;  work is a property;  the net work done by, or on, a closed system undergoing an adiabatic process between two given states depends on the two states and not on the details of the adiabatic process.  About entropy, the correct statement is:  During an internally reversible process, the change of entropy is proportional to the change of enthalpy  Entropy might change during an internally reversible adiabatic process  For an incompressible substance with a constant specific heat, the change of entropy during a process only depends on the temperatures at the initial and final states of the process  Entropy is not necessarily a system property  none of the above is correct
