As we extend our discussion of thermodynamic concepts toward the objective of predicting spontaneity, consider now an isolated system consisting of two flasks connected with a closed valve. Initially there is an ideal gas on the left and a vacuum on the right (Figure 1). When the valve is opened, the gas spontaneously expands to fill both flasks. R...
Ludwig Boltzmann developed a molecular-scale statistical model that related the distribution of matter within a system as the number of microstates possible for the system. A microstate (W)is a specified configuration of a system’s particles and their respective locations and energies. Consider the general case of a system comprised of N particles ...
At the molecular level, Entropy (S) is related to the total number of microstates (W). S= k ln(W) Here S is the entropy, k is the Boltzmann constant with a value of 1.38 × 10−23 J/K, and Wis the number of microstates.
The relationships between entropy, microstates, and matter/energy dispersal described previously allow us to make generalizations regarding the relative entropies of substances and to predict the sign of entropy changes for chemical and physical processes. Consider the phase changes illustrated in Figure 6. In the solid phase, the atoms or molecule...
Entropy is the natural tendency of a system to favor a more uniform dispersal of matter. The more microstates a particular system contains, the greater the entropy of the system. The fewer microstates a particular system contains, the less entropy there is in the system. The applications to chemical systems are summarized here.

Learn how to calculate the number of microstates and macrostates of a system of gas molecules, and how they relate to the dispersal of matter and energy. Explore the concept of entropy and its role in determining spontaneity and relative entropies of substances.
Learn how entropy is related to the number of microstates possible for a system, where a microstate is a specific configuration of locations and energies of atoms or molecules. See examples of how to calculate entropy changes and how they relate to spontaneous processes and heat flow.
Dec 13, 2022 · Learn what a microstate is in chemistry and how it differs from a macrostate. See how microstates relate to entropy and how to calculate the number of microstates using Boltzmann's equation.
In statistical mechanics, a microstate is a specific configuration of a system that describes the precise positions and momenta of all the individual particles or components that make up the system. Each microstate has a certain probability of occurring during the course of the system's thermal fluctuations .
