STATES OF MATTER • The Four States of Matter • Solid • Liquid • Gas • Plasma • Four States

ATOM • Basic unit of matter • Very small • Made up of three

ATOM • Basic unit of matter • Very small • Made up of three particles-proton, neutrons, and electrons

ABSOLUTE ZERO • Theoretical temperature at which atoms would not be moving • It

ABSOLUTE ZERO • Theoretical temperature at which atoms would not be moving • It is -273. 15 degrees celsius or -459. 68 Fahrenheit

STATES OF MATTER Ø Based upon particle arrangement Ø Based upon energy of particles

STATES OF MATTER Ø Based upon particle arrangement Ø Based upon energy of particles Ø Based upon distance between particles

Kinetic Theory of Matter is made up of particles which are in continual random

Kinetic Theory of Matter is made up of particles which are in continual random motion.

STATES OF MATTER SOLIDS • Particles of solids are tightly packed, vibrating about a

STATES OF MATTER SOLIDS • Particles of solids are tightly packed, vibrating about a fixed position. • Solids have a definite shape and a definite volume. Heat

STATES OF MATTER LIQUID § Particles of liquids are tightly packed, but are far

STATES OF MATTER LIQUID § Particles of liquids are tightly packed, but are far enough apart to slide over one another. § Liquids have an indefinite shape and a definite volume. Heat

STATES OF MATTER GAS § Particles of gases are very far apart and move

STATES OF MATTER GAS § Particles of gases are very far apart and move freely. § Gases have an indefinite shape and an indefinite volume. Heat

PHASE CHANGES Description of Phase Change Solid to liquid Term for Phase Change Melting

PHASE CHANGES Description of Phase Change Solid to liquid Term for Phase Change Melting Liquid to Freezing solid Heat Movement During Phase Change Heat goes into the solid as it melts. Heat leaves the liquid as it freezes.

PHASE CHANGES Description of Phase Change Liquid to gas Term for Phase Change Vaporization,

PHASE CHANGES Description of Phase Change Liquid to gas Term for Phase Change Vaporization, which includes Heat goes into the boiling and liquid as it vaporizes. evaporation Gas to liquid Condensation Solid to gas Heat Movement During Phase Change Sublimation Heat leaves the gas as it condenses. Heat goes into the solid as it sublimates.

But what happens if you raise the temperature to super-high levels… between 1000°C and 1, 000, 000°C ? Will everything just be a gas?

STATES OF MATTER PLASMA § A plasma is an ionized gas. § A plasma

STATES OF MATTER PLASMA § A plasma is an ionized gas. § A plasma is a very good conductor of electricity and is affected by magnetic fields. § Plasmas, like gases • Plasma is the have an indefinite common state shape and an of matter indefinite volume.

STATES OF MATTER SOLID Tightly packed, in a regular pattern Vibrate, but do not move from place to place LIQUID Close together with no regular arrangement. Vibrate, move about, and slide past each other GAS Well separated with no regular arrangement. Vibrate and move freely at high speeds PLASMA Has no definite volume or shape and is composed of electrical charged particles
