How do you make metal contract?
They expand ------- No, normally metals expand when heated.
Does metal expand when heated or cooled?
No. A chemical change occurs only when a new substance is produced with new and different properties. In your example, a physical change occurred because only the metal's physical properties were affected. Nothing new was created.
What happens to matter when heated?
When matter is heated it will expand
Why a solid metal expands when it is heated?
Metal expands when it is headed, Because of a process called melting , the more you heat a substance the more it will expand, ( the atoms ) will will get to a point where it will become a liquid and if heated enough the atoms will get so far apart that it will become a gas.
When most solids liquids and gases are heated they?
expand
Why do train tracks expand?

Why a glass jar can be easily opened if the metal lid is heated?
because metal will expand when it has been heated up
Will a metal expand if it's thicker?
Yes, metal will expand when heated regardless of its thickness. Thicker pieces of metal will expand in all dimensions, but the expansion will be proportional to the increase in thickness.
Why does metal get larger when its heated?
yes it does because the paricles expand.
What happens to the electrical conductivity of a metal when it is heated?

Why did concord expand during flight?

How do you make metal contract?

When metal heats up what will it do?
It will expand, and if heated enough, will start to glow and melt.
How are metal bands put on beer barrels?
They are heated to make them expand and trhen they are hammered on.
What happens to metal when it is heated?
The atoms that make up the metal are loosened up by the heat, therefore causing the metal structure to become more flexible.
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.
