Barometer
|
an instrument used to measure the atmospheric pressure
|
|
|
manometer
|
an instrument used to measure the pressure fo fluids and gases in a closed container
|
|
|
STP
|
the conditions of any gas with the temperature 273K and the pressure is at 760 torr and the volume is 22.4 liters
|
|
|
universal gas constant
|
is a physical constant used in equations of state to relate various groups of state functions to one another
PV=nRT |
|
|
standard molar volume
|
one mole of STP will occupy a volume which is 22.4 L or 22,400 mm.
|
|
|
Boyle's Law
|
at constant temperature the pressure of a gas is inversely propotional to its volume
P(1)V(1)=P(2)V(2) |
|
|
Charles' Law
|
at constant pressure the volume of a gas vary directly with its temperature in Kelvin
|
|
|
Ideal Gas Law
|
is the equation of state of a hypothetical ideal gas, first stated by Benoît Paul Émile Clapeyron in 1834.
The state of an amount of gas is determined by its pressure, volume, and temperature according to the equation: where is the absolute pressure [Pa], is the volume [m3] of the vessel containing moles of gas, is the amount of substance of gas [mol], is the gas constant [8.314 472 m3·Pa·K−1·mol−1], is the temperature in kelvins [K]. PV=nRT |
|
|
Torr
|
millimetre of mercury (mmHg) is a non-SI unit of pressure
