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.

28 de nov. de 2021 · Entropy is a measure of the disorder or randomness of a system, and the energy unavailable to do work. Learn how entropy applies to physics, chemistry, and cosmology, and see formulas and examples.
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 (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.
Learn what entropy is and how it relates to the number of possible states for a system. Watch a video and read comments from students and teachers about entropy in chemistry and physics.
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.
30 de jun. de 2009 · Entropy is a thermodynamic property, like temperature, pressure and volume but, unlike them, it can not easily be visualised. Introducing entropy. The concept of entropy emerged from the mid-19th century discussion of the efficiency of heat engines.
