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,…

Through experiments, scientists established the mathematical relationships between pairs of variables, such as pressure and temperature, pressure and…

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…

Unless individual gases chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each…

Chemical stoichiometry describes the quantitative relationships between reactants and products in chemical reactions. In addition to measuring…

The ideal-gas equation, which is empirical, describes the behavior of gases by establishing relationships between their macroscopic properties. For…

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…

The kinetic molecular theory qualitatively explains the behaviors described by the various gas laws. The postulates of this theory may be applied in…

Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many…

Thus far, the ideal gas law, PV = nRT, has been applied to a variety of different types of problems, ranging from reaction stoichiometry and…

Tools to measure lung and airways volume are critical for pulmonary researchers interested in evaluating the impact of disease or novel therapies on…

An analog, macroscopic method for studying molecular-scale hydrodynamic processes in dense gases and liquids is described. The technique applies a…

We demonstrate a method for high-throughput catalyst screening using a parallel pressure reactor starting from the initial synthesis of a nickel…
