Study Notes
What is Metal?
- Metals are naturally occurring materials or combinations of naturally occurring materials.
- Distinguishing characteristic: Shiny and easily bent (malleable).
Where to Find Metals
- Metals are found in rocks called ores, located both above and below the earth's surface.
- Ores contain metals that need to be extracted (mined).
- Mining methods have evolved from simple tools to large-scale mechanized operations.
Physical Properties of Metals
- Shiny: Metals have a characteristic luster.
- Malleable: They can be hammered or pressed into different shapes without breaking (useful for diverse applications).
- Opaque: Light cannot pass through them (unlike glass).
- Excellent Conductors: Electricity & heat can travel easily through metals (important in wiring and cooking).
Metal Conduction
- Metals are good conductors of heat.
- Heat travels quickly through metals, making them suitable for cooking utensils.
How Metals Are Used
- Metals are used in a vast array of applications: Jewelry, wires, cooking utensils, keys, coins, construction materials, automobiles, appliances, and even space-related components (rockets and satellites).
