How does the third law of thermodynamics allow absolute entropies of substances to be determined? A) It defines a reference point by which entropy changes can be measured and assigned as an absolute entropy for a substance. B) It defines the temperature at which all absolute entropies are measured. C) It requires that all energy in a process be conserved to accurately measure an absolute entropy. D) It provides a reference point for the absolute entropy of the universe. E) It requires that a process be reversible to measure the absolute entropy change.

For the process A(l) A(g), which direction is favored by changes in energy probability? Positional probability? Explain your answers. If you wanted to favor the process as written, would you raise or lower the temperature of the system? Explain.
A 220-ft3 sample of gas at standard temperature and pressure is compressed into a cylinder, where it exerts pressure of 2000 psi. Calculate the work (in J) performed when this gas expands isothermally against an opposing pressure of 1.0 atm. (The amount of work that can be done is equivalent to the destructive force of about 1/4 lb of dynamite, giving you an idea of how potentially destructive compressed gas cylinders can be if improperly handled!)
In the thermodynamic definition of a spontaneous process, why is it important that the phrase “continuous intervention” be used rather than just “intervention?”
Can non-pV work be obtained from a process for which G=0? Explain.
Under what conditions is the entropy of a substance equal to zero?
Estimate the entropy change of an 800-lb engine (1lb=0.455kg) that goes from normal environmental temperature, about 20C, to an average operational temperature of 650C. The heat capacity of iron the major component of most engines is 0.45J/gK.

Plants take in CO2(g) and H2O(l) and make glucose, C6H12O6(s), and O2(g). Determine the standard entropy change for the overall reaction.
What is the entropy change for an ideal Carnot cycle? Explain your answer.
The Second Law of Thermodynamics states that entropy increases for spontaneousprocesses and that an increase in entropy is associated with transitions from ordered todisordered states. Living organisms, even the simplest bacteria growing in cultures, appearto violate the Second Law because they grow and proliferate spontaneously. They convertsimple chemical substances into the highly organized structure of their descendants. Writea critical evaluation of the proposition that living organisms contradict the Second Law.Be sure to state your conclusion clearly and to present detailed, reasoned arguments tosupport it.
