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"

Entropy basically talks about the spontaneous changes that occur in everyday phenomena. Learn the meaning of entropy, along with its formula, calculation, and its relation to thermodynamics.
Nov 28, 2021 · Entropy is defined as a measure of a system’s disorder or the energy unavailable to do work. Entropy is a key concept in physics and chemistry, with application in other disciplines, including cosmology, biology, and economics. In physics, it is part of thermodynamics. In chemistry, it is part of physical chemistry.
Often called Shannon entropy, it was originally devised by Claude Shannon in 1948 to study the size of information of a transmitted message. The definition of information entropy is expressed in terms of a discrete set of probabilities so that
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 ...
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.
Sep 29, 2022 · Entropy Definition . Entropy is the measure of the disorder of a system. It is an extensive property of a thermodynamic system, which means its value changes depending on the amount of matter that is present. In equations, entropy is usually denoted by the letter S and has units of joules per kelvin (J⋅K −1) or kg⋅m 2 ⋅s −2 ⋅K −1 ...
May 29, 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.
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.
In thermodynamics, entropy is a numerical quantity that shows that many physical processes can go in only one direction in time. For example, cream and coffee can be mixed together, but cannot be "unmixed"; a piece of wood can be burned, but cannot be "unburned".
