Selena States That Proves That Entropy Has a Definite

question 43

Multiple Choice

Selena states that proves that entropy has a definite value at the beginning and end of an adiabatic free expansion. Ron says , where W is the number of microstates of a given macrostate. Which one, if either, is correct?

• A)Only Selena, because entropy can depend only on macroscopic variables.
• B)Only Ron, because entropy can depend only on microscopic variables.
• C)Only Selena, because in an adiabatic free expansion.
• D)Neither, because we cannot calculate changes in entropy in an adiabatic free expansion.
• E)Both, because entropy, which is macroscopic, is a function of microscopic disorder.
