(P1V1)/(n1T1) = (P2V2)/(n2T2)

V=1/P

V/T

P/T

PV=nRT or V={nRT}/{P}

• homogeneously
• it were the only gas present.

Ptotal = P1 + P2 + P3 +

• Because the volume of an individual gas particle is so small compared to the volume of
• its container, the gas particles are considered to
• have mass, but no volume.

• Gas particles are in constant, random, straight-line motion except when they collide with each
• other or with the container walls.

Collisions are elastic therefore the total kinetic energy (Ek) of the particles is constant.

A = It doubles

The rate of effusion of a gas is inversely related to the square root of its molar mass

1/sqrt{M}

• 1) 1atm
• 2) 760 mm Hg
• 3) 760 torr
• 4) 14.7 lb/sq in
• 5) 1.01325 bar
