Baring some curious complication, heat expands all things. When you put heat into something, it gains some of that energy. If you had warm hands and you gripped a metal rod, the metal rod would slowly heat up, it takes the heat energy from you.
On the smallest scale, heat means a material is moving around and energetic. In a cold gas, the molecules are moving around quite slowly, they have so little energy. Put energy (heat) into the gas and they will speed up and become very active...and even the gas will expand, like with a hot air balloon. (Try freezing an inflated balloon, note how it deflates a bit but re-expands when you warm it in the open air)
So metal is no different, really. The difference is small...and perhaps unnoticeable most of the time. But rest assured, the metal expands slightly due to heat.

Why does water expand at the equator?
Water expands at the equator because it is warm there, and warm molecules expand. Warm molecules expand and cold molecules decrease in size.
What expands quicker aluminium or aluminium bronze?
Yes...brass expands more than iron because brass is a mixture of metal which would expand more when heated..while iron is one metal which is harder to be able to expand. :)
How can you heat and expand metal without using a flame of any kind?
You can expose the metal to hot water or oil.
How much will a metal pipe expand in heat?
This is different for different metals.
Does metal expand when it is heated?
Yes, but it is hard to see unless the object is massive.
How do you make metal contract?
They expand ------- No, normally metals expand when heated.
Why is the cold water poured on a hot metal rim?
it is done to expand it again after fitting the handle to it .when it is don the wooden handle is completely tightly fitted to the metal rim
How would temperature affect bridges?
the metal or concrete might expand if it gets too hot and compress when it gets too cold.
Why does water expand when cold?
Water expands when it is cold because the water molecules found in water expand in the cold.
Why airplane did't expand at the higher altitude?
A balloon would expand because it is flexable and when the outside pressure gets lower it fills out. An airplane actually shrinks in the exterme cold of the upper atmosphere. It is not going to shrink or expand much because it is made out of metal not rubber.
Why do oven trays expand and contract?
heat makes metal expand.
What is denser hot metal or cold metal?
Cold metal.
What is the scientific law of expand and contrast?
Expand- Hot Contrast- Cold
What are metals that expand and contract?
Metals expand when heated because when heat touches the atoms they bounce around even more than they already do so they need more space. When you cool a metal it contracts. Would you get closer to someone when your cold?
When was Cold Metal created?
Cold Metal was created in 2001.
Why does metal expand when warm?
Because the particles
When does metal expand?
When the metal has overhotted the micrometer will overdue and drip. this is when you shut your mouth you understand!!!!!!!!!!!!!!!!!!
