The processes in thermodynamics that go by their own or form product naturally is known as a spontaneous process. In the spontaneous processes, the total energy of the reaction or process must be minimum and the entropy must be maximum.

Standard calculations suggest that the entropy of our universe is dominated by black holes, whose entropy is of order their area in Planck units, although they comprise only a tiny fraction of its total energy. Statistical entropy is the logarithm of the number of microstates consistent with the...
entropy [en´trŏ-pe] 1.in thermodynamics, a measure of the part of the internal energy of a system that is unavailable to do work. In any spontaneous process, such as the flow of heat from a hot region to a cold region, entropy always increases. ...
What is entropy? Entropy: There are various thermodynamic properties of a gaseous matter such as the pressure, volume, temperature, enthalpy, entropy, and specific heat. Some of those properties are intrinsic while others are extrinsic. Of these, many properties are state functions such as entropy...
Entropy, equilibrium, and time Absolute entropies Standard entropies of substances Entropy depends on concentration Summary of key concepts Concept map Entropy is one of the most fundamental concepts of physical science, with far-reaching consequences ranging from cosmology to chemistry. It is also...
This is due to entropy, because the water molecules tend to use up their accumulated potential energy, release heat, and end up with a lower potential energy. Temperature isn't the only transformation involved in entropy. The changes always involve moving from disequilibrium to equilibrium, ...
is much less than both E 2 and E. We want to know the properties of system 1 in equilibrium. Remember that it will be in (or extremely close to) the state that has the largest entropy. For S to be a maximum, dS/dE 1 must be zero. † Let’s write dS/dE 1 a different ...
