Ch. 3 - Matter States of Matter Kinetic Molecular Theory States of Matter
Lesson Objectives I can describe the 4 states of matter in terms of KMT (the energy of the particles and the force of attraction between those particles. I can diagram the way particles will look inside a solid, liquid, and gas.
Kinetic Molecular Theory KMT Particles of matter are always in motion. The kinetic energy (speed) of these particles increases as temperature increases.
4 States of Matter Solids Liquids Gases Plasma
Four States of Matter: Solids Solids very low KE particles vibrate but can t move around Definite shape Definite volume Can t be compressed
Four States of Matter: Liquids Liquids Medium KE particles slide around but are still close together Indefinite Shape Definite Volume Can t be Compressed
Four States of Matter: Gases Gases high KE - particles can separate and bounce throughout container Indefinite shape Indefinite volume Can be Compressed
Four States of Matter: Plasma Plasma very high KE - particles collide with enough energy to break into charged particles (+/-) gas-like, indefinite shape & volume Magnetic fields affect them stars, fluorescent light bulbs, CRTs

Big Ideas The state of matter is determined by how fast the particles are moving and the attraction between them. Kinetic Molecular Theory All substances are in constant motion and the amount of motion is proportional to the temperature.
