Front Back
Defined as the force per unit area on a surface
Pressure (P)
The force that will increase the speed of a one-kilogram mass by one meter per second each second that the force is applied
Newton (N)
A device used to measure atmospheric pressure
Barometer
The common unit of pressure
Millimeters of mercury (mm Hg)
Defined as being exactly equivalent to 760 mm Hg
One atmosphere of pressure
Defined as the pressure exerted by a force of one newton (1 N) acting on an area of one square meter
One pascal (Pa)
The pressure of each gas in a mixture
Partial pressure
States that the total pressure of a gas mixture is the sum of the partial pressures of the component gases. expressed as Pt= P1 + P2 + P3...
Dalton's law of partial pressures
The temperature -273.15 degrees C and is given a value of zero in the Kelvin scale
Absolute zero
The pressure of a fixed mass of gas at constant volume varies directly with the Kelvin temperature. written as P/T = k
Gay-Lussac's law
Expresses the relationship between pressure, volume, and temperature of a fixed amount of gas. expressed as PV/T = k
Combined gas law
At constant temperature and pressure, the volume of gaseous reactants and products can be expressed as ratios of small whole numbers
Gay-Lussac's law of combining volumes of gases
The law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules
Avogadro's law
The volume occupied by one mole of a gas at STP. it has been found to be 22.4 L
Standard molar volume of a gas
The mathematical relationship among pressure, volume, temperature, and the number of moles of a gas. written as PV = nRT
Ideal gas law
