Um gás bidimensional é um conjunto de N ob … Um gás bidimensional é um conjunto de N objetos que são obrigados a mover-se em um espaço planar ou bidimensional em um estado gasoso. Os objetos podem ser: elementos de um gás ideal, tais como um discos rígidos submetendo-se a colisões elásticas; partículas elementares; ou qualquer objeto em física que obedeça leis do movimento. O conceito de um gás bidimensional é usado porque:
* a questão a ser estudada realmente ocorre em duas dimensões (a superfície de certos fenômenos moleculares) ou;
* a forma bidimensional do problema é mais maleável do que o análogo matematicamente mais complexo de problema tridimensional. Enquanto físicos estudaram interações de dois corpos simples em um plano durante séculos, a atenção dada ao gás de duas dimensões (com muitos corpos em movimento) é um exercício do século XX. Aplicações levaram a uma melhor compreensão da termodinâmica dos gases, supercondutividade, determinados problemas de estado sólido e várias questões de mecânica quântica.do e várias questões de mecânica quântica.

The objects can be: classical ideal gas elements such as rigid disks undergoing elastic collisions; elementary particles, or any ensemble of individual objects in physics which obeys laws of motion without binding interactions. The concept of a two-dimensional gas is used either because: 1.
* the issue being studied actually takes place in two dimensions (as certain surface molecular phenomena); or, 2.
* the two-dimensional form of the problem is more tractable than the analogous mathematically more complex three-dimensional problem. While physicists have studied simple two body interactions on a plane for centuries, the attention given to the two-dimensional gas (having many bodies in motion) is a 20th-century pursuit. Applications have led to better understanding of superconductivity, gas thermodynamics, certain solid state problems and several questions in quantum mechanics.nd several questions in quantum mechanics.
