A. Kinetic Molecular Theory
KMT
Tiny, constantly moving particles make up all matter.
The kinetic energy (motion) of these particles increases as temperature increases.

B. Four States of Matter
Solids low KE - particles vibrate but
can’t move around definite shape & volume crystalline - repeating
geometric pattern amorphous - no pattern (e.g.
glass, wax)

B. Four States of Matter
Liquids higher KE - particles can
move around but are still close together
indefinite shape definite volume

B. Four States of Matter
Gases high KE - particles can
separate and move throughout container
indefinite shape & volume

B. Four States of Matter
Plasma very high KE - particles collide with
enough energy to break into charged particles (+/-)
gas-like, indefiniteshape & volume
stars, fluorescentlight bulbs, TV tubes

C. Thermal Expansion
Most matter expands when heated & contracts when cooled.
Temp causes KE. Particles collide with more force & spread out.
EX: thermostats (bimetallic strip)
