1. **Composition:** Wood is primarily composed of cellulose fibers and lignin, which are organic materials. Metals, on the other hand, are composed of metallic elements and have a crystalline structure.
2. **Strength:** Metals are generally much stronger than wood. They have a higher tensile and compressive strength, making them suitable for load-bearing structures. Wood is less strong and is often used for different purposes.
3. **Conductivity:** Metals are excellent conductors of heat and electricity. Wood is a poor conductor of both heat and electricity.
4. **Malleability and Ductility:** Metals are malleable and ductile, meaning they can be hammered into thin sheets (malleability) and drawn into wires (ductility). Wood does not possess these properties to the same extent.
5. **Rust and Corrosion:** Most metals can corrode or rust when exposed to moisture and oxygen. Wood does not rust but can decay when exposed to moisture and certain microorganisms.
**5 Differences Between Metals and Wood:**
1. **Origin:** Metals are typically extracted from ores found in the Earth's crust. Wood comes from trees, which are renewable natural resources.
2. **Weight:** Metals are generally denser and heavier compared to wood. This makes wood easier to work with in some applications.
3. **Flammability:** Wood is flammable, while most metals are not. Some metals may melt or weaken under high heat, but they do not catch fire like wood.
4. **Maintenance:** Metals often require less maintenance compared to wood. Wood may need regular sealing, painting, or other protective measures to prevent decay and damage.
5. **Sound and Thermal Insulation:** Wood provides better sound and thermal insulation compared to most metals. It is often used in construction for its natural insulating properties. Metals are poor insulators in comparison.
