(1.4) Let be a system in contact with three reservoirs: a heat bath, a volume reservoir and a second work reservoir for other work than volume pressure-work (chemical work for instance). Show that the maximum amount of non-pressure-volume work, W', that can be done by I equals-AG. The equality sign only applies for quasi-static processes.

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,...

Q2) In class we showed that you can re-express the Second Law in terms of a system's Gibbs Free Energy. In fact, we can choose any combination of thermodynamic quantities. We can instead choose to define the Combined Potential Φ as Φ-U-TS-μ.NA-μΒΝ. Íor a system that contains molecules of types A and B a) Show that the thermodynamic identity for the Combined Potential is dDSdT- PdV- N.dyl N.dyua. (Hint: the First Thermodynamic Identity for this system is Express entropy, the...

What does the second law of thermodynamics state about energy? When energy transforms, the energy breaks down from a neatly organized state to a state of disarray Thermal energy from a warm object will move into a colder object until all the thermal energy has been transferred. As heat disperses into a colder object, coldness disperses into the heat source until their temperatures are equal O When alowed to do so, localized energy disperses into places where less energy is...

10. According to the first law of thermodynamics, the energy of the universe is constant. Does this mean that AE is always equal to zero? a. Yes, AE = 0 at all times, which is why 9 = -W. b. No, AE does not always equal zero, but this is only due to factors like friction and heat. c. NO, AE does not always equal zero because it refers to the system's internal energy, which is affected by heat and...
