压力和测量压力
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,…
气体定律
Through experiments, scientists established the mathematical relationships between pairs of variables, such as pressure and temperature, pressure and…
理想气体定律的应用:摩尔质量、密度和体积
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…
气体混合物-道尔顿分压定律
Unless individual gases chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each…
化学计量学和气体
Chemical stoichiometry describes the quantitative relationships between reactants and products in chemical reactions. In addition to measuring…
动力学分子理论:基本假设
The ideal-gas equation, which is empirical, describes the behavior of gases by establishing relationships between their macroscopic properties. For…
动力学分子理论与气体定律
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…
分子速度和动能
The kinetic molecular theory qualitatively explains the behaviors described by the various gas laws. The postulates of this theory may be applied in…
渗出和扩散
Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many…
真实气体-偏离理想气体定律
Thus far, the ideal gas law, PV = nRT, has been applied to a variety of different types of problems, ranging from reaction stoichiometry and…
体积摄影与气压面学相结合测量肺结构-功能关系
Tools to measure lung and airways volume are critical for pulmonary researchers interested in evaluating the impact of disease or novel therapies on…
一种研究稠密气体和液体分子流体力学过程的模拟宏观技术
An analog, macroscopic method for studying molecular-scale hydrodynamic processes in dense gases and liquids is described. The technique applies a…
乙烯聚合中使用并联电抗器的压力和链转移聚合的动力学分析
We demonstrate a method for high-throughput catalyst screening using a parallel pressure reactor starting from the initial synthesis of a nickel…
