Pressure

The force per unit area on a surface.

Newton

The force that will increase the speed of a one-kilogram mass by one meter per second each second that the force is applied.

Barometer

A device used to measure atmospheric pressure.

Millimeters of Mercury

The common unit of pressure symbolized by mm Hg.

atomosphere of pressure

Equivalent to 760 mm Hg and is symbolized as atm.

Pascal

The pressure exerted by a force of one Newton acting on an area of one square meter and is symbolized by Pa.

Partial Pressure

The pressure of each gas in a mixture.

Daltons Law of Partial Pressures

States that the total pressure of a gas mixture is the sum of the partial pressures of the component gases.

Boyle's Law

States that the volume of a fixed mass of gas varies inversely with the pressure at constant temperature.

absolute zero

Value of zero on the Kelvin scale.

Charles Law

States that the volume of a fixed mass of gas at a constant pressure varies directly with the Kelvin temperature.

Gay Lussac's Law

The pressure of a fixed mass of gas at a constant volume varies directly with the Kelvin temperature.

Combined Gas Law

Expresses the relationship between pressure, volume, and temperature of a fixed amount of gas.

Gay Lussacs Law of Combining volumes of Gases

States that at constant temperature and pressure, the volumes of gaseous reactants and products can be expressed as ratios of small whole numbers.
