Question 8: A gas sample is compressed from a larger volume to a smaller volume. Which of the following is true? A change in volume has no effect on number of microstates or entropy. The number of microstates available to the system is decreased and the system's entropy is decreased The number of microstates available to the system is increased and the system's entropy is decreased The number of microstates available to the system is decreased and the system's entropy is increased The number of microstates available to the system is increased and the system's entropy is increased Chock

For each situation described in Question 13, predict whether the entropy of the system increases or decreases.

One statement of the second law of thermodynamics is that heat cannot be turned completely into work. Another is that the entropy of the universe always increases. How are these two statements related?
