‭2.3 States Of Matter‬ ‭Kinetic-molecular theory‬ ‭-‬ ‭All matter is composed of tiny particles ( atoms, molecules, or ions)‬ ‭that are in constant motion‬ ‭-‬ ‭The energy determines the the speed of motion of the particles and‬ ‭the greater the amount of energy ( usually thermal ) the faster the‬ ‭motions and the opposite is true as well‬ ‭-‬ ‭Particles would fly apart is they are not limited in some way‬ ‭ tate of matter is determined (differentiated) by kinetic energy of the‬ S ‭particles and the attractive forces between the particles.‬ ‭Solids‬ ‭-‬ ‭have relatively little kinetic energy compared with the attractive forces‬ ‭that are present between particles. The attractive forces significantly‬ ‭limit the movement of the particles which vibrate in a fixed position‬ ‭-‬ ‭Fixed volume and shape‬ ‭-‬ ‭Incompressible‬ ‭Liquids‬ ‭-‬ ‭Their particles have a degree of freedom and have moderate kinetic‬ ‭energy. The particles have enough kinetic energy to partially‬ ‭overcome the attractive forces between them and are slightly more‬ ‭spread apart.‬ ‭-‬ ‭The volume of a liquid is constant (definite)‬ ‭-‬ ‭Liquid takes the shape of the container‬ ‭-‬ ‭Is nearly incompressible‬ ‭Gases‬ ‭-‬ ‭Has enough kinetic energy for its particles to completely overcome all‬ ‭the attractive forces between them so the particles move rapidly in‬ ‭random directions across great distances‬ ‭-‬ ‭Has a variable shape‬ ‭-‬ ‭They are also fluids‬ ‭-‬ ‭Easy to compress‬
