Properties of Matter
Question | Answer |
---|---|
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. |
