Answers

We hope you’ve learnt something new with this Quickfire Quiz. Check your answers here!

1. A. Smooth…
   This is because the path of resistance is much shorter. All metals are primarily shiny, hard solids that are good conductors of heat and electricity. Silver conducts electricity better than any other metal.
2. C. Tool steel…
   Ductile metals, mostly alloys, can withstand heat stress. If tensile force is applied these materials can be stretched into a wire. If compressive force is applied, they can be deformed into sheets. Common ductile materials are copper, aluminum, and steel.
3. B. Mercury’s melting point is cooler than the normal human body temperature…
   Mercury’s melting point is at -38.83ºc but is a liquid at room temperature. It turns entirely into a gas at 356ºc! Other metals melt close to room temperature, for example Gallium will melt in the palm of your hand.
4. A. Brass is antimicrobial…
   The surfaces of brass (and bronze) is natural antimicrobial, which means it kills bacteria. Brass is a copper alloy. All copper alloys are naturally antibacterial.
