What is the density of a metal? (High/Low)
High
Why are Alloys made instead of using original metal?
To strengthen its properties.
Constituent of Bronze.
Tin and Copper.
Improved Properties for Solder.
Low Melting Point.
Uses for Bronze.
Sculptures, coins and instruments. (Any Other Acceptable Answer)
Is rubber a electrical conductor or insulator?

What is the definition of Alloys?
Metal that is made up of mixture of elements.
Constituent of Solder and Sterling Silver.
Solder- Tin and lead.
Sterling Silver- Silver and copper.
Improved Properties for Stainless Steel.

Name 7 alloys.
Steel, Stainless Steel, Duralumin, Bronze, Brass, Sterling Silver, Solder
Constituent of Brass.
Copper, Zinc, Lead and Iron.
Improved Properties for Brass.
More corrosion resistant, More sonorous, able to withstand friction.
Uses for Duralumin.
Aircraft frames, light weight guns, bars and rods for machinery. (Any Other Acceptable Answer)
What is the only metal that is liquid in room temperature?
Mercury
Why are Alloys stronger than pure metals?
They are made up of atoms of different sizes, rather than being uniform. This means that the layers of atoms cannot slide over each other easily.
Constituent of Stainless Steel and Duralumin.
Duralumin- Aluminium and Copper
Improved Properties for Bronze.
More Malleable, More Sonorous, More Resistant to Corrosion.
Uses for Stainless Steel.
Cutlery, Major Electrical Appliances, Surgical Instruments. (Any Other Acceptable Answer)
