A SIMPLE SUMMARY OF THE LAW OF CHEMISTRY

Avogadro's Law

Equal volumes of gases under identical temperature and pressure conditions will contain equal numbers of particles (atoms, ion, molecules, electrons, etc.).

Boyle's Law
At constant temperature, the volume of a confined gas is inversely proportional to the pressure to which it is subjected.PV = k

Charles' Law
At constant pressure, the volume of a confined gas is directly proportional to the absolute temperature.

V = kT

Combining Volumes
Refer to Gay-Lussac's 

LawConservation of Energy

the First Energy can be neither created nor destroyed; the energy of the universe is constant. This is Law of Thermodynamics.

Conservation of Mass
Also known as Conservation of Matter. Matter can be neither created nor destroyed, though it can be rearranged. Mass remains constant in an ordinary chemical change.

Dalton's Law
The pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases.

Definite Composition
A compound is composed of two or more elements chemically combined in a defined ratio by weight.

Dulong & Petit's Law
Most metals require 6.2 cal of heat in order to raise the temperature of 1 gram-atomic mass of the metal by 1°C.

Faraday's Law
The weight of any element liberated during electrolysis is proportional to the quantity of electricity passing through the cell and also to the equivalent weight of the element.

First Law of Thermodynamics
Conservation of Energy. The total energy of the universe is constant and is neither created nor destroyed.

Gay-Lussac's Law
The ratio between the combining volumes of gases and the product (if gaseous) can be expressed in small whole numbers.

Graham's Law
The rate of diffusion or effusion of a gas is inversely proportional to the square root of its molecular mass.
