PHYSICAL CHEMISTRY
Ideal gas - no interactions between particles
- particles have no volume
- particles have no volume
pV = nRT obeyed
exactly
R = Gas Constant = 8.314 Pa m3 K-1 mol -1
STP Standard Temperature and Pressure
T = 0oC (273.15K) p = 1 atm (1.013x105Pa)
1 mol of ideal gas = 22.41 L at STP.
The nature
of the gas is not important as
long as the gas behaves as an ideal gas.
