T or F: The change in entropy of a closed system between two specified states depends on whether the process is reversible or irreversible.
Added by Thomas W.
Step 1
Entropy is a measure of the disorder or randomness in a system. In thermodynamics, it is a state function, meaning it depends only on the initial and final states of the system, not on the path taken to get from one state to the other. Show more…

Indicate whether each statement is true or false. (a) The entropy of the universe increases for any spontaneous process. (b) The entropy change of the system is equal and opposite that of the surroundings for any irreversible process. (c) The entropy of the system must increase in any spontaneous process. (a) The entropy change for an isothermal process depends on both the absolute temperature and the amount of heat reversibly transferred.
True or false? ΔS for a single-component system in going from T1, P1 to T2, P2 is higher for an irreversible than for a reversible process. Explain.

Indicate whether each statement is true or false. (a) The second law of thermodynamics says that entropy can only be produced but cannot not be destroyed. (b) In a certain process the entropy of the system changes by $1.2 \mathrm{~J} / \mathrm{K}$ (increase) and the entropy of the surroundings changes by $-1.2 \mathrm{~J} / \mathrm{K}$ (decrease). Thus, this process must be spontaneous. (c) In a certain process the entropy of the system changes by $1.3 \mathrm{~J} / \mathrm{K}$ (increase) and the entropy of the surroundings changes by $-1.2 \mathrm{~J} / \mathrm{K}$ (decrease). Thus, this process must be reversible.
