Their molecules and atoms becomes tight and forms in that shape that they have been kept mostly for liquids.
The particles will contract.
When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.
its a movement of small particles of matter
ummm it will definetely expand....if the materials you"re talking about is the term for science.
At the feezing point the liquid become a solid.Freezing is a physical change.
The particles will contract.
colder
Particles vibrate faster when they are heated.
colder
it loses energy that makes it not move as quickly, therefore it gets smaller. that answer your question?
because the particles of the compound, called atoms, vibrate more when heated and then when cooled the
ereee
A solid's particles already vibrate in relatively fixed positions. However, when the solid is cooled enough, the particles will likely vibrate even less.
When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.
When a gas is heated up, the particles within the gas start to move faster, going farther apart (expansion). When a gas is cooled, the particles slow down and it starts to condense (contract), and if cooled enough, into a liquid.
If you understand by particles atoms they remain unchanged.
