5 Assumptions of the KMT
1) Gases are mainly empty space
2) Collisions are elastic-no KE lost (vs. Real Gases)
3) Particles are in constant, random, and rapid motion
4) No attractive or repulsive forces between particles (vs. Real Gases)
5) KE=1/2mv^2
When Real Gases approach Ideal Gas behavior

Properties of Gases
1) Compressible
2) Low Density (g/L)
3) Expandable
4) Diffusable
