2. Introduction to entropy - Wikipedia

   en.wikipedia.org/wiki/Introduction_to_entropy

   However, today the classical equation of entropy, = can be explained, part by part, in modern terms describing how molecules are responsible for what is happening: Δ S {\displaystyle \Delta S} is the change in entropy of a system (some physical substance of interest) after some motional energy ("heat") has been transferred to it by fast-moving ...

3. Entropy - Wikipedia

   In more detail, Clausius explained his choice of "entropy" as a name as follows: [10] I prefer going to the ancient languages for the names of important scientific quantities, so that they may mean the same thing in all living tongues. I propose, therefore, to call S the entropy of a body, after the Greek

   Figure 1. A thermodynamic model system. Differences in pressure, density, and temperature of a thermodynamic system tend to equalize over time. For example, in a room containing a glass of melting ice, the difference in temperature between the warm room and the cold glass of ice and water is equalized by energy flowing as heat from the room to the cooler ice and water mixture.

5. Entropy (order and disorder) - Wikipedia

   en.wikipedia.org/wiki/Entropy_(order_and_disorder)

   However, there is a broad class [18] of systems that manifest entropy-driven order, in which phases with organization or structural regularity, e.g. crystals, have higher entropy than structurally disordered (e.g. fluid) phases under the same thermodynamic conditions. In these systems phases that would be labeled as disordered by virtue of ...

6. Entropy as an arrow of time - Wikipedia

   en.wikipedia.org/wiki/Entropy_as_an_arrow_of_time

   Entropy is one of the few quantities in the physical sciences that require a particular direction for time, sometimes called an arrow of time. As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease. Thus, entropy measurement is a way of distinguishing the past from ...

7. Principle of minimum energy - Wikipedia

   en.wikipedia.org/wiki/Principle_of_minimum_energy

   The maximum entropy principle: For a closed system with fixed internal energy (i.e. an isolated system), the entropy is maximized at equilibrium. The minimum energy principle: For a closed system with fixed entropy, the total energy is minimized at equilibrium.

   Alistair Berg / Getty Images As we age, our brain experiences both structural and functional changes. Over time, this can cause a decline in cognitive abilities, memory, and even emotional regulation.

9. Temperature–entropy diagram - Wikipedia

   en.wikipedia.org/wiki/Temperature–entropy_diagram

   In thermodynamics, a temperature–entropy (T–s) diagram is a thermodynamic diagram used to visualize changes to temperature (T ) and specific entropy (s) during a thermodynamic process or cycle as the graph of a curve. It is a useful and common tool, particularly because it helps to visualize the heat transfer during a process.
