| Atmospheric pressure | Pressure that results for the collisions of air molecules with objects. greatest in low elevations |
| Average kinetic energy | particles in a collection at any temp. have a wide range of kinetic energies. used to discuss the kinetic energy of the particles in a collection, higher temp= higher kenetic energy |
| Gas particles | Insignifigant volume, no attractive forces, move rapidly in a constant motion, move in strait paths |
| H=mHv | H= heat energy in joules, m= mass in grams, Hv= Heat of Vaporization |
| Kenetic Molecular Theory | The tiny particles of matter are in constant motion |
| Kenetic Temperature Scale | used to reflect the relationship between the average kinetic energy, absolute zero= no molecular motion |
| Latent Heat of Vaporization | amount of heat neded to boil a substance, used to break intermolecular forces, not change the temperature, more energy is needed to break intermolecular forces than to loosen them, need more energy to boil than to melt |
| Liquids | Particles are free to flow and take the shape of their container |
