Properties of metals |
Solid at room temperature Iron, Nickel and Cobalt are magnetic Conducts electricity and heat Mercury is a liquid |
|
|
What do the words DUCTILE, SONOROUS AND MALLEABLE mean? |
Ductile=can be drawn into a wire Sonorous=makes a sound when struck Malleable=can bend and shape easily |
|
|
What are these things used for. Aluminum, Copper, Gold, Iron, and Mercury? |
Aluminum=low density-aircraft parts Copper=electrical conductor-electrical wires Iron=very strong=bridges and cars, high tensile strength Mercury=liquid at room temperature- thermometers |
|
|
What is Tarnishing? |
Tarnishing occurs when a metal loses its shine. Metals react with air and water which = thin layer of Tarnish. IRON+OXYGEN+ WATER----IRON OXIDE |
|
|
How to stop rusting. |
Galvanishing= when a layer of Zinc stops the oxygen and water from hitting the metal. Painting and Greasing= stops oxygen and water reaching the metals. Electroplating. |
