Properties of Matter Unit Components Physical Properties Characteristic Properties States of Matter Mixtures and Solutions Matter: Anything that has mass and takes up space Mass: •the amount of matter in an object •measured with a balance Volume: •the amount of space an object takes up •measured with a ruler or graduated cylinder Physical Properties Are characteristics or features that describe matter Are true only for a certain amount of matter Examples include color smell size temperature shape state texture Characteristic Properties Are properties that do NOT change as mass, volume and/or shape change. Are properties of a substance, not a specific object Examples include boiling point hardness melting point pH solubility flammability conductivity density Because characteristic properties are usually not affected by physical changes, they can be used to identify matter States of Matter Solid Liquid Gas Plasma The Molecule Chamber Demonstrates the movement of particles of matter in the various states in which it occurs. Increased temperature increases particle movement and the space between them. The particles of water behave differently because of the make up of the molecule Solids •Have definite shape and definite volume •Particles are tightly packed Liquids •Do not have definite shape but do have definite volume •Particles are loosely packed Gases •Do not have definite shape or definite volume •Particles are very far apart Phase Changes of Water melting evaporating ICEfreezing WATERcondensing STEAM (solid) (liquid) (gas) Properties of Matter include: How it looks (shiny, dull, colored) How it feels (hard, soft, rough, smooth) How it smells (sweet, salty, flowery) How it sounds (loud, soft, hollow) How it tastes (sweet salty, bitter, sour) What it does (bounce, bubble, tear) Examples of Physical Properties/Changes: Mass Mixture Volume Solution Shape Odor Texture State Examples of Chemical Properties/Changes: Burning Rusting Cooking Film Processing (Any change that causes NEW matter to be formed) Characteristic Properties are...  properties that do not change with changes in mass or volume  examples include: density boiling point melting point freezing point Welcome to the Wonderful World of Science …more exciting adventures will follow…
