Charles Law

V =kT

Boyle’s Law

V= k 1/P

http://dbhs.wvusd.k12.ca.us/GasLaw/Gas-Boyle.html

Generalised Gas Equation : P₁V₁ = P₂V₂

T₁ T₂

http://dbhs.wvusd.k12.ca.us/GasLaw/Gas-Combined.html

And PV = nRT

Calculations using these equations

Phase Diagrams:

P vs T, P vs V

Variation from ideal by Real Gasses

Corrections to Gas Equation

Van der Waals Equation:

(P + an²/V²) x (V – nb) = nRT

PV = nRT

Calculation of Molecular weight of vapors

And volumes of masses of a liquid.
