thermodynamics, the entropy of fusion is the increase in entropy when melting a solid substance. This is almost always positive since the degree of disorder increases...

Entropy is a scientific concept that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used...

enthalpy (H) and the entropy (S), known respectively as the enthalpy of fusion (or latent heat of fusion) and the entropy of fusion. Melting is therefore...

to an entropy effect resulting from higher molecular symmetry. Indeed, the entropy of fusion of neopentane is about four times lower than that of n-pentane...

A high melting point results from a high heat of fusion, a low entropy of fusion, or a combination of both. In highly symmetrical molecules the crystal...

between the β and α forms represents the melting of the silver (cation) sublattice. The entropy of fusion for α-AgI is approximately half that for sodium...

thermodynamics, the entropy of vaporization is the increase in entropy upon vaporization of a liquid. This is always positive, since the degree of disorder increases...

neopentane's significantly lower entropy of fusion. The branched isomers are more stable (have lower heat of formation and heat of combustion) than n-pentane...

the standard molar entropy is the entropy content of one mole of pure substance at a standard state of pressure and any temperature of interest. These are...

the melting point of components. The composition and temperature of a eutectic can be calculated from enthalpy and entropy of fusion of each components...

The principle of maximum entropy states that the probability distribution which best represents the current state of knowledge about a system is the one...

In the history of physics, the concept of entropy developed in response to the observation that a certain amount of functional energy released from combustion...

High-entropy alloys (HEAs) are alloys that are formed by mixing equal or relatively large proportions of (usually) five or more elements. Prior to the...

is called the enthalpy of fusion, i.e. ΔH for ice fusion. The entropy of the surrounding room decreases less than the entropy of the ice and water increases:...

Sensor fusion is a process of combining sensor data or data derived from disparate sources so that the resulting information has less uncertainty than...

entropy of an ideal gas is proportional to the logarithm of its pressure. The entropies of liquids vary little with pressure, as the coefficient of thermal...
