States of Matter

There are Four States of Matter Solid Liquid Gas Plasma

Solids Particles are very close together Have orderly, fixed arrangements Fixed volumes due to fixed positions Particles can only vibrate in position

Liquids More random arrangement of particles than solids. Particles are loosely held together by attractive forces between particles, but can move past one another. Result: Liquids can flow into any shape, but have a definite volume

Attractive forces between liquid particles may result in: Cohesion Attraction for each other Adhesion Attraction to other materials Capillary Action Ability to “climb” due to cohesion and adhesion Surface Tension Force that act on the surface of a liquid and that tends to minimize the area of the surface

Gas Essentially independent particles. Large space between particles result in little to no attraction between particles. Result: Gases can flow into any shape, and have no definite volume

Plasma Supercritical fluid Occurs at very high temperatures and very high pressures Has properties of both the liquid phase and the gas phase
