- DictionaryEn·tro·py/ˈentrəpē/
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"
The meaning of ENTROPY is a measure of the unavailable energy in a closed thermodynamic system that is also usually considered to be a measure of the system's disorder, that is a property of the system's state, and that varies directly with any reversible change in heat in the system and inversely with the temperature of the system; broadly ...
One dictionary definition of entropy is that it is "a measure of thermal energy per unit temperature that is not available for useful work" in a cyclic process. For instance, a substance at uniform temperature is at maximum entropy and cannot drive a heat engine.
Nov 28, 2021 · Entropy is a measure of the randomness or disorder of a system. Its symbol is the capital letter S. Typical units are joules per kelvin (J/K). Change in entropy can have a positive (more disordered) or negative (less disordered) value. In the natural world, entropy tends to increase.
Jul 31, 2024 · Entropy, the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, entropy is also a measure of the molecular disorder, or randomness, of a system.
Nov 30, 2023 · Entropy: The Invisible Force That Brings Disorder to the Universe. By: Jesslyn Shields | Updated: Nov 30, 2023. Entropy describes how disorder happens in a system as large as the universe or as small as a thermos full of coffee. Jose A. Bernat Bacete/Getty Images.
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.
ENTROPY definition: 1. the amount of order or lack of order in a system 2. a measurement of the energy in a system or…. Learn more.
Entropy is a measure of disorder. You walk into a room and see a table with coins on it. You notice they are all heads up: HHHHHH. "Whoa, that seems unlikely" you think. But nice and orderly, right? You move the table and the vibration causes a coin to flip to tails (T): HHHHTH.

The second law of thermodynamics is best expressed in terms of a change in the thermodynamic variable known as entropy, which is represented by the symbol S. Entropy, like internal energy, is a state function.
