In this lesson our instructor talks about the ideal gas equation. He discusses pressure, barometer, and the Boyle's law. Then he talks about gas laws and the Avogadro's law. He ends the lesson with a lecture on the ideal gas equation, standard temperature and pressure.
Pressure is defined as Force per Area, and its SI unit is the Pascal
Ideal Gas Law: PV = nRT. This equation expresses a relationship among the various measureable quantities of a given gas sample. It might better be written as PV/nT = R.
In other words, given a sample of gas, its Pressure times the volume it occupies divided by the number of mols of gas times its Kelvin temperature is equal to a Constant.
When some mathematical arrangement of parameters is equal to a constant, this is profoundly important.
R is the Gas Constant: 0.08306 Liter-Atmosphere/Mol-Kelvin
Units used must match the units of R.
Standard Temperature and Pressure (STP) is 0 K and 1 atm.
