Gases - (Chemistry)

Gases respond to changes in

pressure, volume, temperature, number of particles

Pressure is symbolized as

P

Volume is symbolized as

V

Temperature is symbolized as

T

Number of particles is symbolized as

n

Boyle’s Law

pressure-volume relationship

Pressure-volume relationship

at constant temperature, volume is a fixed mass of gas is inversely proportional to pressure

Boyle’s Law formula

P_1(V_1) = P_2(V_2)

Charles’ Law

temperature-volume relationship

Temperature-volume relationship

at constant pressure, the volume of a gas is directly proportional to its absolute temperature (Kelvin)

Charles’ Law formula

V1/T1 = V2/T2

Gay-Lussac’s Law

temperature pressure relationship

Temperature-pressure relationship

at constant volume, pressure of a gas is directly proportional to absolute temperature

Gay-Lussac’s Law formula

P1/T1= P2/T2

Combined Gas Law formula

P_1(V_1)/T_1 = P_2(V_2)/T_2

Ideal Gas Law formula

PV = nRT

Ideal Gas Law includes

amount of gas (moles, n) and unifies all gas relationships

Gas Stoichiometry

in chemical reactions, coefficients = both molecules ratios and volume ratios (for gases at same T, P)
