Conveys the idea of a force, a push that tends to move something in a given direction.
Pressure
(The SI unit of pressure is N/m^2) it is given the name
Pascal
Corresponds to te typical pressure at sea level, is the pressure sufficient to support a cloumn of mercury 760 mm high.
Standard atmospheric pressure
atm
Atmosphere
torr
Torricelli
the volume if a fixed quantity of gas maintained at a constant temperature is inversely proportional to the pressure.
Boyle's law
The volume of a fixed amount of gas maintained at a constant pressure is .directly proportional to its absolute temperature
Charles's law
Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules
Avogadro's hypothesis
The volume of a gas maintained at constant temperature and pressure is directly proportional to the number of moles of the gas.
Avogadro's law
A hypothetical gas whose pressure, volume, and temperature behavior is completely described by the ideal-gas equation.
Ideal gas
The tem R in the ideal-gas equation.
Gas constant
The conditions 0c and 1 atm
Standard temperature and pressure
(STP)
The pressure exerted by a particular component of a mixture of gases
Partial Pressure
A dimensionless number that expresses the ratio of the number of moles of one component to the total number of moles in the mixture.
Mole fraction
Developed over a period of about 100 years, culminating in 1857 when Rudolf Clausius published a complete and satisfactory form of the theory.
Kinetic-molecular theory
This quantity is the speed of a molecule possessing average kinetic energy.
Root-mean-square (rms) speed
The escape of gas molecules through a tiny hole into an evauated space.
Effusion
The spread of one substance throughout a space or throughout a second substance.
Diffusion
The average distance traveled by a molecule between collisions.
mean free path
