That depends on what type of material. Some will become more ridged and some will become very brittle.
When materials are heated, the particles gain kinetic energy and move faster, leading to expansion of the material. Conversely, when materials are cooled, the particles lose kinetic energy and move slower, causing the material to contract or condense.
They shrink in size. If you carefully control how you cool heated materials, you can make precise bends in them.
it blows
It freeseez.
they expand
It contracts.
it will solidify.
is it when thet get smaller
They freezee
It contracts. solid
i. dont.know
this is known as liquifaction if the gas is cooled to liquid.
