Aim: Explain Kinetic Molecular Theory Notes 12-1

Gases and Gas Pressure

Column of air 1.0m 2 through Upper atmosphere 10,300kg of air 1 atm = 760mm Hg 101,325 Pa

1.) KMT A.) Assumptions: Gases….. 1.) are in random motion. 2.) have negligible volumes 3.) have no interaction between particles 4.) have collisions that are elastic 5.) The kinetic energy of the particles is proportional to the temperature (K)

B.) NO such thing as an ideal gas C.) Two gases are closest to ideal 1.) hydrogen and helium

D.) Most ideal conditions are 1.) high temp 2.) low pressure 3.) Need the most space and the most energy (speed)
