The Four States of Matter Solid Liquid Gas Plasma Chumbler - Properties of Matter
Classifying the Four Types Classify them based upon… particle arrangement energy of particles distance between particles Chumbler - Properties of Matter
1. Solids Particles are tightly packed, very close together, and vibrate about a fixed position Solids have a definite shape and a definite volume. Chumbler - Properties of Matter
Two types of solids: • 1. Crystalline – the particles form a regular, repeating pattern. • It has a specific melting point. • Examples: salt, sugar, snow • 2. Amorphous- the particles are not arranged in a regular pattern • It may become softer or change into other substances at different temperatures. • Examples: plastic, rubber, butter, glass Chumbler - Properties of Matter

2. Liquids Particles are tightly packed, but are far enough apart to slide over one another. Liquids have an indefinite shape and a definite volume. A liquid can also be called a fluid – “substance that flows” Chumbler - Properties of Matter
Liquids Particle Movement Examples Chumbler - Properties of Matter
Properties of Liquids • Surface tension – is the result of an inward pull among the molecules of a liquid that bring the molecules on the surface closer together. Chumbler - Properties of Matter
Properties of Liquids • Viscosity- a liquid’s resistance to flowing • High viscosity flow slowly • Ex: Honey • Low viscosity flow quickly • Ex: Water • Viscosity video Chumbler - Properties of Matter
3. Gases Particles are very far apart and move freely. Gases have an indefiniteshape and an indefinite volume. Chumbler - Properties of Matter

4. Plasma an ionized gas. a very good conductor of electricity and is affected by magnetic fields. Plasma, like gases have an indefinite shape and an indefinite volume. Chumbler - Properties of Matter
Plasma Particles The negatively charged electrons (yellow) are freely streaming through the positively charged ions (blue). Chumbler - Properties of Matter
