A flame is a striking manifestation of combustion, which consists of the intense combination of a substance with oxygen. The reaction with oxygen can be mild such as rust, spontaneously occurring in iron e...
A system in thermodynamic equilibrium must be stable. This means to say that small perturbations do not remove the system from its equilibrium.
Brazilian/Portuguese names are usually very long, and mine is not particularly an easy one. In case you wish to cite me, keep in mind the following: my last name is "Oliveira".
Many random phenomena are made up by a set or by a succession of independent trials and therefore described by independent random variables.
Mario de Oliveira: Muitas vezes acabamos ficando por mau humor devido à atitude negativa de outras vizinhos, que têm a oportunidade de não deter nada a ver conosco. Pode ser incrivelmente desgastante lidar utilizando pessoas negativas.
When we are outdoors on a sunny day we feel the effects of heat on our skin even if the environment is at a low temperature. Likewise, when we are near the fire, we feel more heat on the surface of more info our body that is exposed to fire read more than on the opposite surface. These effects are caused by radiative heat transfer from the emitting source, the sun or...
We study the heat transport properties of a chain of coupled quantum harmonic oscillators in contact at its ends with two heat reservoirs at distinct temperatures.
We study in this daniel dantas facebook chapter the phase diagrams of multicomponent systems. The representation that provides the simplest diagrams is that composed only by thermodynamic fields.
Liquid crystals are substances which exhibit thermodynamic phases intermediate between crystalline solid and ordinary liquid, called mesophases, which are distinct from both ordinary liquid and crystalline solid.
According to Sommerfeld, the well known Clausius and Kelvin statements of the second law of thermodynamics comprises two parts.

In this chapter we consider systems with stochastic dynamics, governed by master equations and defined on a lattice. The system to be studied comprises a lattice with N sites.

A solid substance is characterized by having a spatial structure consisting of a three-dimensional lattice at whose vertices the atoms are located.
