Bizmuth is a heavy metal that expands on cooling and contracts on heating. it is used for making lead free ammunition, especially for shotgun rounds and airgun pellets as it is considered non-toxic. It is also used in the glass making industry for making 'float' glass sheets.

How does a thermometer detect temperature?
Matter generally expands as it warms, and contracts as it cools. In liquid thermometers, as the liquid heats and expands, it is directed up a tube with markings to show the exact amount of expansion. In Bi-metal thermometers, there is a strip of two different metals pressed together. These metals expand and contract at different rates. As a result, the strip will coil and uncoil with the rise and fall of the temperature. A needle attached to this coil can show the temperature.
Can aluminum produce sparks?
Depends what you heating source is. Generally no.. If you want to see sparks from heating a metal use Magnesium.
What is a piece of metal with cooling fins that can be attached to an integrated chip to dissipate heat?
It's called a Heat Sink.
What does metal from heaven come from?
As far as I know, there is no metal that comes from heaven. All the metal that is there stays there and all the metal here stays here.
What is a metal burr?
A metal burr is a small, thin edge of metal that is created when a piece of metal is machined. For example: when a chef's knife is sharpened, a thin piece of metal remains on the edge of the knife.
What state of matter expands with cold and contracts with heat?
Well, solids. For example, when you heat up metal is expands and when you freeze it, it contracts
How does heating or cooling affect metal?
Heating metal can cause it to expand, increasing its volume and potentially altering its shape and strength. Cooling metal can cause it to contract, reducing its volume and potentially making it more brittle. Rapid heating or cooling can also lead to thermal stress and distortions in the metal.
Is Eiffel Tower always the same height?
no ,Because when the temperature increases the metal expands and when the temperature is low the metal contracts
What is distortion in arc welding?
Distortion in arc welding refers to the warping or bending of a metal workpiece that occurs due to uneven heating and cooling during the welding process. As the metal is heated, it expands, and upon cooling, it contracts; this differential movement can lead to misalignment or changes in shape. Factors such as the welding technique, the type of joint, and the material being welded can influence the extent of distortion. Managing distortion is crucial for maintaining the integrity and dimensional accuracy of the final welded structure.
When metal is heated and expands will the metal get larger or smaller?
When metal is heated, it expands and becomes larger in size. This is because heating the metal causes the atoms to vibrate more, which in turn increases the space between them, resulting in expansion.
Why bimetallic strip bend in curve instead of showing linear expansion on heating?
If one metal expands or contracts at a different rate than the other, and they are bonded together, as they are in a bimetallic strip, a curve is inevitable - it physically has to happen, if you think about it.
When heating metal will volume and mass change?
When heating metal, its volume typically expands due to thermal expansion, which causes the atoms in the metal to vibrate more and spread out. The mass of the metal will not change during heating unless there is a chemical reaction taking place, such as oxidation.
What is a liquid metal that expands and contracts as the temperature changes and is the metal used in thermometers called?
The liquid metal used in thermometers that expands and contracts as temperature changes is mercury. Mercury is commonly used due to its unique properties, such as its wide liquid temperature range and high thermal conductivity, making it ideal for accurate temperature measurement.
Why does blacksmith heat the iron rim for a wooden wheel before putting it into place?
Heating makes the iron expand so the rim circle is bigger than when it cools. Thus when applied hot is shrink when in place, holding the wheel together tightly.
What is the scientific term for heating metal and then rapidly cooling?
The scientific term for heating metal and then rapidly cooling it is "quenching." This process helps to alter the metal's physical properties, such as hardness and strength, by inducing a rapid transformation within its atomic structure.
Why a tightly fitting metal cap is opened by heating it slightly?
The metal cap has a high expansion coefficient when temperature rises. As it expands and the grip loosens.
Fuel source that was used in china that impressed Marco?
the heating and then quick cooling of the metal adamantium
