Properties of Matter

Matter Everything that has mass and volume All solids, liquids, and gases.
Solid Volume & shape stay the same Atoms are tightly packed & vibrate in place
Crystalline atoms are arranged in a regular pattern to make crystals
Amorphous atoms are not arranged in a pattern.
Liquid Volume stays the same Shape changes to fit its container Atoms are more loosely packed & move around each other
High viscosity Ex: Honey Flows slowly
Low viscosity Ex: Water Flows quickly
Gas Can change shape & volume Atoms are very far apart and move around very quickly
Melting Changing from a solid to a liquid
Freezing Changing from a liquid to a solid
Vaporization Changing from a liquid to a gas
Condensation Changing from a gas to a liquid
Sublimation Changing from a solid to a gas without passing through the liquid phase
Physical Properties Characteristics of a substance that can be observed without changing it into another substance.
Physical Change A change that alters the form or appearance of a material, but does NOT make the material into another substance.
Chemical Properties A characteristic of a substance that describes its ability to change into different substances.
Chemical Change A change in which one or more substances combine or break apart to form NEW substances.
Endothermic Absorbs heat energy from surroundings Feels cold Ex: Baking Soda & Vinegar
Exothermic Gives off heat to the surroundings Feels hot Ex: A fire
The Law of Conservation of Mass The total amount of matter is neither created nor destroyed in any physical or chemical change.
