Jan 30, 2023 · Entropy is a state function that is often erroneously referred to as the 'state of disorder' of a system. Qualitatively, entropy is simply a measure how much the energy of atoms and molecules become more spread out in a process and can be defined in terms of statistical probabilities of a system or in terms of the other thermodynamic quantities.
Entropy is the measure of the amount of missing information before reception. Often called Shannon entropy, it was originally devised by Claude Shannon in 1948 to study the size of information of a transmitted message.
Entropy is a measure of the number of microstates available to a system, which increases when matter or energy becomes more dispersed. Learn how to calculate entropy using Boltzmann's equation and see examples of entropy changes in different situations.

Jan 13, 2022 · Entropy (S) is a state function whose value increases with an increase in the number of available microstates. A reversible process is one for which all intermediate states between extremes are equilibrium states; it can change direction at any time.
Entropy is a thermodynamic state function that measures the randomness or disorder of a system. Learn how to calculate entropy using statistical probability or thermodynamic quantities, and see how it relates to the Second Law of Thermodynamics and chemical reactions.
Entropy is a measure of disorder and microstates of a system. Learn how entropy relates to heat, temperature, and the Second Law of Thermodynamics, and how it affects chemical processes.
