Question
On a microscopic level, the entropy of a system increases with the number of available microstates, which are the possible arrangements of the positions and kinetic energies of the particles in the system. These states cannot be examined individually but are instead studied by using statistical analysis. Each thermodynamic system has a unique number of microstates associated with it, designated as W. Entropy increases with the number of microstates
Consider a system consisting of a cylinder with a movable piston containing 106 gas molecules at 298 K at a volume of 1 L. Consider the following descriptions of this system:
A) Initial system, as stated in the problem statement.
B) Starting from the initial system, the volume of the container is changed to 2 L and the temperature to 395 K.
C) Starting from the initial system, a combination reaction occurs at constant volume and temperature.
D) Starting from the initial system, the gas reacts completely to produce 107 gas molecules at 395 K in a volume of 2 L.
E) Starting from the initial system, the temperature is changed to 395 K at constant volume.
Arrange the descriptions in order of increasing number of microstates in the resulting system.
Rank from most to fewest microstates. To rank items as equivalent, overlap them

Answer:
The items are arranged as follows:
A) Initial system, as stated in the problem statement.
D) Starting from the initial system, the gas reacts completely to produce 107 gas molecules at 395 K in a volume of 2 L.
C) Starting from the initial system, a combination reaction occurs at constant volume and temperature.
E) Starting from the initial system, the temperature is changed to 395 K at constant volume.
B) Starting from the initial system, the volume of the container is changed to 2 L and the temperature to 395 K.
Explanation:
The increase in the number of molecules results in the increase in the number of microstates. This results in the possible arrangements of the molecules. Apart from that, there is an increase in the volume of the container as the increase of the volume increases the number of positions where individual molecules can be found. Thus, the order above shows how the microstates increase.
