What happens to the density if an object is cooled?
If an object is cooled, the particles within the object will lose kinetic energy and move closer together. This results in an increase in the density of the object because the same mass is now packed into a smaller volume.
Why most objects expand when heated and contracts when cooled?
when objects are heated they gaining energy and the molecules begin to vibrate and bounce off each other, causing them to get farther apart, the opposite is true when an object is "cooled" ( i air quote cooled because in truth the word cold is somewhat unnecessary as you can heat can be gained, but there is no such thing as gaining cold only losing heat, so a better word would be something like "unwarm", or in this case "unheated").
What happens to particles when materials are heated or cooled?
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.
How fast do molescules move when object is cooled?
That depends how cool you make the molecules. Theoretically at Absolute zero (0k) molecules are supposed to cease to vibrate. I say theoretically, because absolute Zero is unobtainable and also it doesn't take into account movement at the Quantum scale.
What happens with water vapor when its cooled?
when water vapour is cooled it condenses and falls as rain

When an object is cooled the bonds in that object?
strengthen
When an object is cooled what happens to with thermal energy?
It's transferred - so something gets warmer.
What happened to the mass of an object when it is cooled?
Nothing happens to the mass when its cooled (or heated).Mass is the same (law of Conservation of Mass).Volume can change, though, which affects density (since mass is constant).
How can a object cool?
an object can be cooled by air or by a fridge or freezer.
What happens when helium is cooled?
it blows
What happens to a liquid when it is cooled?
It freeseez.
What happens to tar when its cooled?
it will solidify.
What happens when rocks are cooled?
they expand
What happens to metal when cooled?
It contracts.
What happens to the particle in a substance when it is cooled?
i. dont.know
What happens to liquids when cooled?
It contracts. solid
