How This Is Calculated


$$ PV = nRT $$ where:

P   =   Pressure   (Pa)

V   =   Volume   (m3)

n   =   Number of moles   (mol)

R   =   Ideal Gas Constant   (J/molK)

T   =  Temperature   (K)


Assumptions


  • Molecular size is negligible.
  • There are no intermolecular forces.
  • Gas molecules are in constant, random motion and collisions are elastic.
