Pressure
The force per unit area on a surface. (P)
Barometer
A device used to measure atmospheric pressure.
Average atmospheric pressure at sea level at 0°C
760 mm Hg or 1 atm
One atmosphere of pressure (atm) is equal to ______ mm Hg.
760
Unit of pressure
pascal (Pa)
Standard pressure
1 atmosphere
Standard temperature
0°C or 273 K
The pressure of each gas in a mixture
Partial Pressure
Dalton's law
The total pressure of a gas mixture is the sum of the partial pressures of the component gases.
Boyle's law
The volume of a fixed mass of gas varies inversely with the pressure at constant temperature.
Absolute Zero
The temperature -273°C, given a value of zero in the Kelvin scale.
Charles's Law
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.
Avogadro's law
That equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
Ideal gas law
The mathematical relationship among pressure, volume, temperature, and the number of moles of a gas.
Ideal Gas Constant
The constant R. It's value depends on the units chosen for pressure, volume, and temperature.
Graham's law of effusion
That the rates of effusion of gases at the same temperature and pressure are inversely proportional to the square roots of their molar masses.
Volume occupied by one mole of an ideal gas at STP
22.4 L / mol
Charles's law, Boyle's law, and Avogadro's law
PV = nRT

Kinetic-molecular theory

Based on the idea that particles of matter are always in motion

Newton

Unit of force
