MATTER Solids, Liquids, & Gases I. States of Matter w Kinetic Molecular Theory w Four States of Matter w Thermal Expansion
A. Kinetic Molecular Theory ö KMT w Tiny, constantly moving particles make up all matter. w The kinetic energy (motion) of these particles increases as temperature increases.
B. Four States of Matter ö Solids w low KE - particles vibrate but can’t move around w definite shape & volume w crystalline - repeating geometric pattern (e. g. graphite, diamond) w amorphous - no pattern (e. g. glass, wax)
Types of Solids http: //www. theory. tifr. res. in/~tridib/images/solid. png
B. Four States of Matter ö Liquids w higher KE - particles can move around but are still close together w indefinite shape w definite volume
B. Four States of Matter ö Gases w high KE - particles can separate and move throughout container w indefinite shape & volume
B. Four States of Matter ö Plasma w very high KE - particles collide with enough energy to break into charged particles (+/-) w gas-like, indefinite shape & volume w stars, fluorescent light bulbs, TV tubes
C. Thermal Expansion ö Most matter expands when heated & contracts when cooled. ö Temp causes KE. Particles collide with more force & spread out. ö EX: thermostats (bimetallic strip)
Changes in State II. Changes in State 1. Phase Changes 2. Heating Curves
A. Phase Changes ö Melting w solid to liquid ö Freezing w liquid to solid ö melting point = freezing point
A. Phase Changes ö Vaporization (boiling) w liquid to gas at the boiling point ö Evaporation w liquid to gas below the boiling point ö Condensation w gas to liquid
A. Phase Changes ö Sublimation w solid to gas w EX: dry ice, freeze drying, iodine
A. Phase Changes
B. Heating Curves ö Kinetic Energy w motion of particles w related to temperature ö Potential Energy w space between particles w related to phase changes
B. Heating Curves Gas - KE Boiling - PE Liquid - KE Melting - PE Solid - KE
B. Heating Curves ö Heat of Fusion w energy required to change from solid to liquid w some attractive forces are broken
B. Heating Curves ö Heat of Vaporization w energy required to change from liquid to gas w all attractive forces are broken w EX: steam burns, sweating, and… the drinking bird HEATING CURVE
