The ideal gas equation

View the video - introduction to the ideal gas equation

This equation contains four variables and if we know any three we can solve the equation to find the forth.
The units used for the equation are very important and we must be consinstent in their use. We will use SI units in this chapter. eg:
T =Temperature is in degrees Kelvin
P = Pressure is expressed in kilopascals (kPa)
V = Volume in litres
n = mole of the gas under investigation
R = 8.31JK-1mole-1

Converting units of pressure
Converting units of volume
Converting units of temperature.
