Unit 2 Properties of Matter
| Term | Definition |
|---|---|
| Conductivity | physical property of an object to transmits electricity, heat, or sound |
| Luster | physical property of an object to shine; observed without touching a substance |
| Malleability | physical property of an object to be molded, shaped, or hammered into sheets without breaking |
| Ductility | physical property of an object to be stretched into thin wires |
| Hardness | physical property of an object measured by the resistance of a surface by another substance |
| Streak | physical property of an object by the color of powder produced when a substance is dragged across a rough surface |
| Characteristics of Metals | *high conductivity of electricity, heat, or sound |
| Characteristics of Metals | *high ductility |
| Characteristics of Metals | *high density |
| Characteristics of Metals | *opaque as a thin sheet |
| Characteristics of Metals | *usually a solid at room temperature ( Mercury , liquid, is the exception.) |
| Characteristics of Metals | *dented or flattened by a hammer |
| Characteristics of Metals | *high malleability |
| Characteristics of Metals | *high luster or shine |
| Characteristics of Non-Metals | *poor conductivity of electricity, heat, or sound |
| Characteristics of Non-Metals | *good insulators |
| Characteristics of Non-Metals | *dull in color |
| Characteristics of Non-Metals | *poor conductivity of electricity, heat, or sound |
| Characteristics of Non-Metals | *weak and brittle |
| Characteristics of Non-Metals | *low density |
| Characteristics of Non-Metals | *transparent as thin sheets |

| Density | mass divided by volume |
| Mass | measured in grams |
| Volume | measures in cm3 or mL |
| Density | measure of the compactness of a substance |
| Color | physical property of an object due to the way the object reflects light; observed without touching a substance |
