Page 1: The Kinetic Theory of Matter • All matter is made of particles that are in constant motion. • The faster particles move, the higher the temperature of the substance. • At the same temperature, bigger particles move slower
Page 2: SOLIDS • Particles of solids are tightly packed, vibrating about a fixed position. • Solids have a definite shape and a definite volume. Heat
Page 3: 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
Page 4: GAS • Particles of gases are very far apart and move freely. • Gases have an indefinite shape and an indefinite volume. Heat
STATES OF MATTERPLASMA • ionized gas. • very good conductor of electricity and is affected by magnetic fields. • have an indefinite shape and an indefinite volume. The most common form of matter. Found in the stars and in space between them. Makes up over 99% of the visible universe and perhaps most of that which is not visible.
Some places where plasmas are found… 1. Flames
3. Aurora (Northern Lights) Form when plasma collides with gas particles in the upper atmosphere.
STATES OF MATTER LIQUID PLASMA SOLID GAS Tightly packed, in a regular pattern Vibrate, but do not move from place to place Close together with no regular arrangement. Vibrate, move about, and slide past each other Well be separated with no regular arrangement. Vibrate and move freely at high speeds Has no definite volume or shape and is composed of electrical charged particles
Temperature and Heat Temperatureis the average kinetic energy of the particles in an object. • Higher temperature = higher kinetic energy
Temperature and Heat The total kinetic energy of all the particles in a substance is called thermal energy.
Absolute zerois the point where no more heat can be removed from a system, according to the absolute or thermodynamic temperature scale. This corresponds to 0 K (Kelvin) or -273.15°Cand -459.67°F
