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.
