What are the different types of medals?
Different metals are Platinum. Gold. Silver, or silver-gilt, which is in fact used for Olympic “gold medals” Bronze. Pewter. Copper. Tin. Iron.
Metals from which groups might be used to provide a protective coating?
Metals from groups 13-15 could be used. The metals in these mixed groups are not very reactive, and so could provide protection against corrosion.
Are people made out of metal?
Metal in its natural state is a mineral occurring in the form of ore. It then needs to be mined, extracted from the ore and processed to make whatever. So a metal object is man made from a naturally occurring material. Unless of course it was made by a woman.
What physical and chemical properties are used to separate metals from their ores?
Some impurities ,or unwanted substances ,are less dense than water ,so they float in water and can be washed away.Others ,like sulfur ,can be burned away.
Is a metal an element?
Metals are a class of elements. A pure metal is an element. Some metals are alloys, which mean they have more than one metal or element in them. The metal bronze is made of two elements, the metal tin and the metal copper.
Tests to identify metals?
There are many different tests that can be used to identify different metals. Using a magnet is a popular test to distinguish metals.
Why are two different metals used to produce movement in bimetal elements?
Two different metals are used in bimetal elements because they have different coefficients of thermal expansion. When heated or cooled, these metals expand or contract at different rates, causing the bimetal strip to bend. This bending motion is used for various applications such as in thermostats or circuit breakers.
What is coining is use for?
Different metals are used in different coins depending on the country and type of coin. In the US, the main metals used are copper, zinc, nickel, and sometimes silver and manganese.
Bimetallic strips composed of two different metals each having a different rate of thermal expansion are used in?
Bimetallic strips composed of two different metals with different rates of thermal expansion are used in devices like thermostats and thermometers. When these strips are heated or cooled, they bend due to the different expansions of the metals, which can be used to control switches or indicate temperature changes.
How are electromagnets used in recycling metals?
Electromagnets are used in recycling metals to separate ferrous metals from non-ferrous metals. When a magnet is applied to a mixture of metals, only the ferrous metals (which are magnetic) are attracted to the magnet. This allows for efficient sorting and separation of different types of metals for recycling purposes.
How can decisions be reached about which metals to use when building?
check the comparison of different metals that are used for buildings and then agree on one of them
Could a magnet be used to sort six different materials into metals and non metals?
No, some metals (Aluminum and Gold, etc.) are non-magnetic.
What are used in an electrochemical cell?
Two different metals and a conducting fluid.
What are used in electrochemical cell?
Two different metals and a conducting fluid.
What metal element used for making jewellery?
Many different metals are used. Jewelry is often based on certain expensive metals such as gold, platinum, or silver, but other metals are used as well.
What are the materials used in metal?
Mix of different metals and carbon and/or silicum in alloys
What are the different types of colored metal used in jewelry making?
The different types of colored metals used in jewelry making include gold, silver, copper, brass, and bronze. These metals can be used in their natural form or plated with other colors such as rose gold or black rhodium for a different look.
