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,…
Leis de Gases
Through experiments, scientists established the mathematical relationships between pairs of variables, such as pressure and temperature, pressure and…
Aplicações da Lei de Gás Ideal: 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…
Mistura de Gases - Lei de Dalton de 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…
Estequiometria Química e Gases
Chemical stoichiometry describes the quantitative relationships between reactants and products in chemical reactions. In addition to measuring…
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…
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 do Gás Ideal
Thus far, the ideal gas law, PV = nRT, has been applied to a variety of different types of problems, ranging from reaction stoichiometry and…
Combinando a capnografia volumétrica e pletismografia barométrica para medir a relação estrutura-função do pulmão
Tools to measure lung and airways volume are critical for pulmonary researchers interested in evaluating the impact of disease or novel therapies on…
Uma técnica macroscópica analógica para estudar processos hidrodinâmicos Molecular em densas Gases e líquidos
An analog, macroscopic method for studying molecular-scale hydrodynamic processes in dense gases and liquids is described. The technique applies a…
Polimerizações etileno utilizando reatores de pressão paralelas e uma análise cinética da cadeia de transferência de Polimerização
We demonstrate a method for high-throughput catalyst screening using a parallel pressure reactor starting from the initial synthesis of a nickel…
