A person who works with precious metals and stones is called a jeweler or a gemologist. Jewelers create and design jewelry pieces using metals and stones, while gemologists specialize in identifying and grading gemstones.
Different metals have different behavior in this sense.
Gold is one of the few metals that occurs in its pure state in nature. Gold pieces found are called nuggets.
Yes - they will concentrate stresses
These are the electrodes.
This is called cementation.
large pieces of the lithosphere that move around on the asthenosphere are called Tectonic Plates.
The large pieces of the lithosphere that move around on the asthenosphere are called tectonic plates. These plates are constantly shifting and interacting with each other, resulting in various geological phenomena such as earthquakes and volcanic activity.
To extract precious metals from a catalytic converter, the converter is first crushed into small pieces. These pieces are then heated to high temperatures to burn off any organic materials. Next, the remaining metal is dissolved in acid to separate the precious metals like platinum, palladium, and rhodium. These metals are then further processed and purified for reuse.
It isn't. It's called soldering when you join two pieces of metals together using a 3rd metal with a very low melting point. Welding, then both the "parent" metals and the added metals are melted. Usually at a lot higher temperature.
They are the two electrodes: anode and cathode.
small pieces of coal are called slack. Thank you!
