... 5 POINTS TOTAL (5 points) SOLUTION We need two Key Ideas here. One is that we can determine the entropy change for the irreversible process by calculating it for a reversible process that provides the same change in volume. The other is that the temperature of the gas does not change in the free exp ...

... Definition: (Equilibrium State, State Variables) An equilibrium state is one in which all the bulk physical properties of the system are uniform throughout the system and do not change with time. An equilibrium state is specified by two independent variables known as state variables. Definition: (Th ...

... Objects with a density ___________________ than water will ________________________. 6. Although steel has a density almost _____ times that of water, a steel ship will float if its shape causes it to displace a volume of water greater than its weight thus changing the ship’s density. B. Fluids and ...
