volume of of any any amount amount of of an an ideal ideal gas gas or or any

any mixture mixture of of ideal ideal gases. gases. Ideal Gases Ideal gases are imaginary gases that perfectly fit all of the assumptions of the kinetic

molecular theory. Gases consist of tiny particles that are far apart relative to their size. Collisions between gas particles and between particles and the walls of the container are elastic collisions No kinetic energy is lost in Ideal Gases

(continued) Gas particles are in constant, rapid motion. They therefore possess kinetic energy, the energy of motion There are no forces of attraction between gas particles The average kinetic energy of gas particles depends on temperature, not on the identity

of the particle. Real Gases Do Not Behave Ideally Real gases DO experience intermolecular attractions Real gases DO have volume Real gases DO NOT have elastic collisions Deviations from Ideal

Behavior Likely to behave nearly ideally Gases at high temperature and low pressure Small non-polar gas molecules Likely not to behave ideally

Gases at low temperature and high pressure Large, polar gas molecules The Combined Gas Law The combined gas law expresses the relationship between pressure, volume and temperature of a fixed amount of gas.

P1V1 P2V2 T1 T2 Boyles Law Pressure is inversely proportional to volume when temperature is held constant.

P1V1 P2V2 A Graph of Boyles Law Charless Law The volume of a gas is directly proportional to temperature, and extrapolates to zero at zero Kelvin. (P = constant)

V1 V2 T1 T2 Temperature MUST be in KELVINS! A Graph of Charles Law Gay Lussacs Law The pressure and temperature of a gas are directly related, provided that the volume

remains constant. P1 P2 T1 T2 Temperature MUST be in KELVINS! A Graph of Gay-Lussacs Law Daltons Law of Partial

Pressures For a mixture of gases in a container, PTotal = P1 + P2 + P3 + . . . This is particularly useful in calculating the pressure of gases collected over water.
