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 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.
Entropy is a measure of randomness or disorder of a system that can be applied in various fields such as physics, chemistry, and information theory. Learn the thermodynamic definition, properties, formula, and relation of entropy with different laws of thermodynamics.
- The triple point defines a situation of simultaneous equilibrium between the solid, liquid and gas phases. The entropy of the gas phase is higher t...
- Water has a greater entropy than ice, and so entropy favours melting. Freezing is an exothermic process; energy is lost from the water and dissipat...
- It just says that the total entropy of the universe can never decrease. Entropy can decrease somewhere, provided it increases somewhere else by at...
- Since no finite system can have an infinite number of microstates, it’s impossible for the entropy of the system to be infinite. In fact, entropy t...
- If entropy is the amount of disorder, negative entropy means something has less disorder or more order. The shirt is now less disordered and in a s...
