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 |
