noun
- 1. a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system: "the second law of thermodynamics says that entropy always increases with time"
- 2. lack of order or predictability; gradual decline into disorder: "a marketplace where entropy reigns supreme"

Nov 28, 2021 · Entropy is a measure of the disorder or randomness of a system, and the energy unavailable to do work. Learn how to calculate entropy, see examples of entropy in physics and chemistry, and explore the second law of thermodynamics and the heat death of the universe.
Entropy is a measure of the unavailable energy or disorder in a system, especially in thermodynamics and communication theory. Learn the etymology, examples, and related words of entropy from Merriam-Webster Dictionary.
Thermodynamic entropy is an extensive property, meaning that it scales with the size or extent of a system. In many processes it is useful to specify the entropy as an intensive property independent of the size, as a specific entropy characteristic of the type of system studied.
May 29, 2024 · Entropy is a measure of the thermal energy unavailable for useful work and the molecular disorder of a system. Learn how entropy relates to the second law of thermodynamics, heat engines, and spontaneous processes with examples and equations.
Entropy is a measure of the amount of disorder or randomness in a system or process. Learn how entropy is used in physics, chemistry, statistics and other fields, and see examples of entropy in sentences.

Entropy definition: (on a macroscopic scale) a function of thermodynamic variables, as temperature, pressure, or composition, and differing from energy in that energy is the ability to do work and entropy is a measure of how much energy is not available.
