I don't know someone answer me please !
A solid contracts when it cools down and expands upon heating.
That is why electric wires are not laid taut on electric poles.
Pure water is one of them ie. ice
Metals contract when cooled.
No it does not
yes, because the cooling process removes energy from the matter which makes the particles move less and the matter contract
No. They expand.
Most solids shrink as they get colder (ice is an exception). Some solids become brittle when they are very cold and can shatter if struck.
contract means when a substance becomes small due to cooling or locomotion.
Mostly they expand as they warm, contract as they cool.
All solids contract while cooling.
Usually cooling will cause solids to contract. That is, they will get slightly smaller.
When cooled gases change to liquids (usually) and then solids Solids don't change to gases upon cooling
yes, because the cooling process removes energy from the matter which makes the particles move less and the matter contract
No
No. They expand.
No.
Amorphous solids are formed by the rapid cooling of a liquid. Then, when cooled the particles have no regular pattern like crystaline solids do.
Most solids shrink as they get colder (ice is an exception). Some solids become brittle when they are very cold and can shatter if struck.
At night, there is no sun, thus there is no heat. When there is no heat, solids contract. The wires, being solids contract at night and in the morning, when there is heat, they sag.
yes they do
By applying heat
