(1.5) According to the second law of thermodynamics, which state function assumes either an extremum in equilibrium for (a) an isolated system (no exchange of energy with reservoirs), (b) a system coupled to a heat bath and volume reservoir. Is the extremum a maximum or a minimum?
The second law of thermodynamics states that a. we can get more out of a process than we put in. b. we cannot get more out of a process as we put in. c. we can get out of a process exactly when we put in. d. two bodies are in thermal equilibrium when they both have the same temperature. e. work and temperature are the same thing.
Second Law of Thermodynamics Learning Goal: To understand the implications of the second law of thermodynamics. The second law of thermodynamics explains the direction in which the thermodynamic processes tend to go. That is, it limits the types of final states of the system that naturally evolve from a given initial state. The second law has many practical applications. For example it explains the limits of efficiency for heat engines and refrigerators. To develop a better understanding of this law,...

The first law of thermodynamics In thermal physics, we are often interested in the internal energy (E) of a system. The wo 41 internal energy of an ideal gas is proportional to the temperature and the number of moles of the gas. The internal energy can change when energy is exchanged with the system's environment (ie., objects that are outside the system of interest). The case above is one in which the internal energy of a gas changes due to...
The second law of thermodynamics means that ____. a) the entropy of an isolated system can decrease Yes/No b) the entropy of a system can decrease if the entropy of its surrounding increases by a larger amount Yes/No c) heat can spontaneously flow from a colder body to a hotter body Yes/No d) a system tends to go to a final state which has a smaller number of possible mechanical states Yes/No
1. If a system undergoes a reversible process, a it must be possible to restore the system to its original state. b it must be possible to restore the surroundings to their original state. c it must be possible to restore both the system and the surroundings to their original states. d it is impossible to restore either the the system or the surroundings to their original states. e the system must not interact with its surroundings. 2. According to...
According to the Second Law of Thermodynamics A. the total entropy changes in any reaction that occurs spontaneously must be greater than 0.
