Metals, like most solids will contract when cooled. When cooled the atoms or molecules slow down, vibrating less often, causing a smaller average separation between them.

When a piece of metal cools it will do what?
it will contract
When metal is cooled by ice what will the particles do?
The particles will contract.
What degree does metal contract at?
Contraction occur at low temperature.
Why do oven trays expand and contract?
heat makes metal expand.
What is distortion in welding?
it moves Because almost all Elements expand when heated and contract when cooled. As you are welding the metal at that location is trying to expand because of the heat. Ahead of the weld area the metal isn't moving. Behind the weld area the metal is trying to contract as it cools. If the whole weld could be heated at once it would expand then contract at the same rate without distortion.
Can contract be used as a verb?
Yes, "contract" can be used as a verb to describe the act of making a formal agreement or reducing in size. For example, "They need to contract with the supplier for the new materials" or "The metal will contract as it cools."
What changes do you see when hot metal is cooling?
The metal object would contract, i.e it would shrink.
How can you buy an alloy?
If it is one of the hundreds of standard alloys you can just buy it from a store that sells metal. If not it will be more complex as you will need to contract with a metal supplier to make it fore you.
How do you make metal contract?
They expand ------- No, normally metals expand when heated.
How does temperature make an acoustic guitar out of tune?
The tune of a guitar has got to do with the tension on the metal strings. Temperature causes metal to contract or expand, changing the tension of the strings and thus the tuning.
How you can get the metal lid in the jar should you heat it or cool it?
You can try heating the metal lid to expand it and make it easier to open the jar. Alternatively, you can cool the metal lid to contract it, which may also help loosen its grip on the jar.
If metal expands when hot why do the iron knobs on the wood burning stove get tight when it cools?
When the metal parts are being heated they do not all expand at the same rate depending on size and even on the composition of the metal and what type of alloy's are being used for the handle and the base unit. When cooled all the parts will return to their manufactured size and shape because the metal will contract again as it cools. In this instance with a stove if you were to supercool the entire stove that handle would probably contract so much that you wouldn't be able to even open the door.
