Summary of Gas relationships:

V = volume; P = pressure; T = temperature (K); n = number of moles of gas

Volume and Pressure – Boyle’s Law:

V a 1/P [T & n constant]

Temperature and Volume – Charles Law:

V a T [P & n constant]

Volume and Quantity m- Avogadro’s Law:

V a n [T & P constant]

Ideal Gas Law (combination of the above relationships)

P×V = n×R×T

[R is the gas constant = 0.08206 L×atm×mol^-1×K^-1 = 8.314 J×mol^-1×K^-1]

Variations on Ideal Gas Law:

P-V: P_i×V_i = P_f×V_f

P-T: P_i /T_i = P_f/T_f
