One thing that happens is that the molecules in the matter lose energy and momentum and slow down, therefore the matter becomes more compact.
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
When energy is removed from matter, the matter typically cools down and its particles slow down in movement. This can lead to changes in the physical state of the matter, such as condensation or solidification. However, the matter itself remains the same in terms of its chemical composition.
Use particle theory of matter to describe what happens to the density of a substance when it cools down
guess
It expands and cools
as air cools, the space it occupies becomes less. this result in an increas density
As air cools, the space it occupies becomes less. This results in an increase in density.
When matter cools from being hot, the particles lose kinetic energy and slow down, causing them to come closer together. This results in a decrease in their movement and an overall decrease in volume. At a certain point, the particles may form ordered structures, transitioning from a gas to a liquid or a liquid to a solid.
It forms igneous rock.
it cools
It becomes a Igneous rock.
the density increases
