Kinetic molecular theory
Kinetic molecular theory
The theory proposed to account for the observed behavior of gases. The theory considers gas
molecules to be pointlike, volumeless particles, exhibiting no intermolecular forces and in constant
random motion, undergoing only completely elastic collisions with the container or other
molecules. See Ideal gas law.
Law of conservation of mass
Law of conservation of mass
The law stating that in a given reaction, the mass of the products is equal to the mass of the
reactants.
Law of constant composition
Law of constant composition
The law stating that the elements in a pure compound are found in specific weight ratios.Le Châtelier’s principle
Le Châtelier’s principle
The observation that when a system at equilibrium is disturbed or stressed, the system will react
in such a way as to relieve the stress and restore equilibrium. See Equilibrium.
