Copper shrinks when it cool because of Thermal Expansion.
Sources:
It was a question in my science book,
and I got the question right.
P.S. Would you like to know what Thermal Expansion is?

What will happen when copper is heated?
The copper wire glows red. Once it cools...the copper reacts with the air to produce copper(II) oxide. This is shown by the black tarnish on the copper wire.
If you used nitric acid to dissolve copper how could you remove the copper nitrate?
Heat the liquid to boil off excess water and the copper nitrate will crystalise out of the solution as it cools. Then filter to separate the crystals from the liquid.
What happens when a piece copper wire is heated in the outer region of the flame until its red hot?
The copper wire glows red. Once it cools...the copper reacts with the air to produce copper(II) oxide. This is shown by the black tarnish on the copper wire.
If brass is an alloy of copper and zinc and they exist as solids how is an alloy of brass made?
Copper and Zinc are melted down to liquid state. Then the two metals are combined in some difficult to explain process. When the liquid metal cools, the alloy Brass is formed.
What happens when you heat copper sulphate over a Bunsen burner?
I think it becomes a black liquid which, when it cools becomes a black powder. it also bubbles and gives off a gas (oxygen I think) that means that the copper sulfate had the oxygen removed making it copper sulfide. (I'm not entirely sure but this is what happened in the practical. Cheers.

When will a telephone wire be longer summer or winter?
When metals (like the copper in the telephone wires) gets exposed to heat, they expand (thermal expansion) and when the get cooled they shrink. This directly implies that cables are longer in summer when it is hot. So telephone wires are longer in the summer.
How much does copper pipe shrink?
That would depend on the temperature /pressure as the coeffient of expansion per degree

How is copper concertration smelted in a modern commercial plant?
copper is smelted using a temperature of 800 -1000c it is then put into 3-6 containers then it cools down in the 3 containers
How much heat is lost when 640 g piece of copper cools from 375 celsius to 26 celsius?
86000j

If you take a helium balloon from inside a warm house to outside on a snowy day what will happen to the balloon could you classify this as a phase change?
As the warmer air inside the balloon cools, the balloon will shrink slightly. The amount of shrinkage will depend on the temperature change.
Why would a cake separate from the sides?
As a cake cools it begins to shrink away from the sides of the pan. This is normal.

What happens to atoms when cooled?
as the atom cools down it comes back in its orignal shape .it will be in its contracting form
