Which symbol represents entropy?
Answer and explanation
Correct answer: S
Entropy is the thermodynamic state function conventionally represented by S. It is associated with the dispersal of energy and the number of accessible microscopic arrangements; in the second law, the entropy of an isolated system does not decrease for a spontaneous process. H represents enthalpy, G represents Gibbs free energy, and E is not the standard symbol for entropy. Therefore, option A is correct.
