Entropy is simply a quantitative measure of what the second law of thermodynamics describes: the spreading of energy until it is evenly spread. The meaning of entropy is different in different fields. It can mean: Information entropy, which is a measure of information communicated by systems that are affected by data noise.

Simple introduction to entropy, entropy and nature. Introduction. The second law of thermodynamics is a powerful aid to help us understand why the world works as it does — why hot pans cool down, why our bodies stay warm even in the cold, why gasoline makes engines run.

Metaphoric definition of entropy. Entropy is a concept used in Physics, mathematics, computer science (information theory) and other fields of science. You may have a look at Wikipedia to see the many uses of entropy. Yet, its definition is not obvious for everyone. Plato, with his cave, knew that metaphors are good ways for explaining deep ...

Entropy is a measure of chaos, of the degree of disorder. The higher the entropy, the more disordered, the messier things are. Your bedroom, for example, is likely in a high entropy state of being, while your parents' room is relatively low entropy. [That was my input, sorry.] Humpty Dumpty before the great fall was low entropy.

Entropy definition 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 : the ...

The measure of the level of disorder in a closed but changing system, a system in which energy can only be transferred in one direction from an ordered state to a disordered state. Higher the entropy, higher the disorder and lower the availability of the system's energy to do useful work.Although the concept of entropy originated in thermodynamics (as the 2nd law) and statistical mechanics, it...

Thermodynamic entropy is the measure of how unconstrained energy spreads out (dissipates) over time and temperature, measured as energy over temperature (joule per kelvin). That is, in any energy transformation process, some “energy quantity” always becomes “unavailable to do work” — that “unusable” quantity is entropy.

In Boltzmann's definition, entropy is a measure of the number of possible microscopic states (or microstates) of a system in thermodynamic equilibrium. Consistent with the Boltzmann definition, the second law of thermodynamics needs to be re-worded as such that entropy increases over time, though the underlying principle remains the same.

Thermodynamic entropy is a measure of how organized or disorganized energy is present in a system of atoms or molecules.It is measured in joules of energy per unit kelvin. Entropy is an important part of the third law of thermodynamics.. Imagine that a group of molecules has ten units of energy. If the energy in those molecules is perfectly organized, then the molecules can do ten units of work.

Entropy is a measure of the energy dispersal in the system.. We see evidence that the universe tends toward highest entropy many places in our lives. A campfire is an example of entropy. The solid wood burns and becomes ash, smoke and gases, all of which spread energy outwards more easily than the solid fuel.
