Answer:
The relationship between the number of microstates and entropy is A) Directly proportional.
Step-by-step explanation:
The relationship between the number of microstates and entropy is directly proportional. In statistical mechanics, entropy is a measure of the number of possible microscopic arrangements or microstates that correspond to a macroscopic state. As the number of microstates increases, so does the entropy. This is due to the fact that a system with more microstates has a higher degree of disorder and, consequently, higher entropy.
When a system undergoes changes or transitions, the distribution of its microstates changes, affecting the overall entropy. An increase in the number of microstates corresponds to an increase in disorder, leading to a higher entropy value. Conversely, a decrease in microstates is associated with a decrease in entropy.
Option A is correct.
