Document Summary

Main difference between the states is the difference of dense. Water molecules (liquids) move past each other. Assume the volume and shape of their container. Mix evenly and completely when combine (if you spray perfume, it tries to reach a state of equilibrium in the room so it spreads out evenly) Four important properties to consider: pressure, volume, temperature, quantity. Gases are made of small particles moving in constant, random, straight-line motion. Gas particles have negligible volume (assume zero ) Gas particles are separated by great distances. Collision between particles are rapid and elastic (assume no interaction) No attractive or repulsive forces between gas particles. Average kinetic energy (1/2mv^2) of the particles is proportional to the temperature in k. Total amount of force exerted per unit area in unit of pascals (pa) You can only figure out a gas" pressure when it"s in a container. Pressure exerted by a liquid depends on the height and density of the liquid.
