Gases

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…

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 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…

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…
