Gases
Pressão e Medição da Pressão
Gas pressure is caused by force exerted by gas molecules colliding with the surfaces of objects. Although the force of each collision is very small, any ...
Leis dos Gases
Through experiments, scientists established the mathematical relationships between pairs of variables, such as pressure and temperature, pressure and ...
Aplicações da Lei dos Gases Ideais: Massa Molar, Densidade, e Volume
The volume occupied by one mole of a substance is its molar volume. The ideal gas law, PV = nRT, suggests that the volume of a given quantity of gas ...
Mistura de Gases - Lei de Dalton das Pressões Parciais
Unless individual gases chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each gas ...
Estequiometria Química e Gases
Chemical stoichiometry describes the quantitative relationships between reactants and products in chemical reactions.
In addition to measuring quantities ...
Teoria Cinética Molecular: Postulados Básicos
The ideal-gas equation, which is empirical, describes the behavior of gases by establishing relationships between their macroscopic properties. For ...
Teoria Cinética Molecular e as Leis dos Gases
The test of the kinetic molecular theory (KMT) and its postulates is its ability to explain and describe the behavior of a gas. The various gas laws ...
Velocidades Moleculares e Energia Cinética
The kinetic molecular theory qualitatively explains the behaviors described by the various gas laws. The postulates of this theory may be applied in a ...
Efusão e Difusão
Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many ...
Gases Reais - Desvio da Lei dos Gases Ideais
Thus far, the ideal gas law, PV = nRT, has been applied to a variety of different types of problems, ranging from reaction stoichiometry and empirical and ...
