(a)What is the difference between a state and a microstate of a system?
(b) As a system goes from state A to state B, its entropy decreases What can you say about the number of microstates corresponding to each state?
(c) In a particular spontaneous process, the number of microstates available to the system decreases. What can you conclude about the sign of ?Ssurr?
