it is malleable
No. Copper (the metal, an element) has chemical properties. The shape of the copper (wire) does not affect it's chemical behavior.
No. If you leave some copper wire in a square box it will never come out in a square shape.
Nitrogen atoms are similar in shape and size to Carbon atoms
Physical. It is simply changing the shape or configuration of solid copper to another shape. Chemical changes cannot be reversed.
Copper Sulfate is actually like powder so it doesn't have a particular shape, but if you dissolve it in water and leave for some days it can turn into diamond-shaped, blue stones.
No. Copper (the metal, an element) has chemical properties. The shape of the copper (wire) does not affect it's chemical behavior.
Copper is used because of its ductile property, meaning that they bend into shape easily
Retains geometric shape
The shape of copper is globular
Because the shape is sturdier, the shape makes it easy for the buildings to go high into the air and last because the shape makes it easier to go high into the air.
Yes, it is. You aren't altering the chemical composition at all - it's still copper - you are merely changing its shape.
For strength of brick constructions it is useful to have them partially overlapping. A rectangular shape makes it easier to have them partly overlapping.
It has a streamline body shape for it to overcome air resisitance
The shape makes funneling liquids or fluids easier.
Copper is a solid shape, so it has a definite shape and volume.
They have a distinct goblet like shape, that makes producing mucus easier.
Ergonomics. The shape makes them easier to deploy en masse, makes them easier to stack together for storage, and takes up less space than a number of other shapes.
