压力和测量压力
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, any ...
气体定律
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
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 of gas ...
气体混合物-道尔顿分压定律
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 gas ...
化学计量学和气体
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 quantities ...
动力学分子理论:基本假设
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
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
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 a ...
渗出和扩散
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
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 empirical and ...
