Hi,
lets look at this from "bottom to top", that is: Solid state, Liquid State , Gaseous State.
starting with the solid state molecules have virtually no kinetic energy and so they stick together in one bulk... now suppose we put this mass on a source of heat, the molecules will gain energy from the heat and start to vibrate rapidly until they partially break free from the bulk, this indicates that we started going to the liquid phase and if we wait a little more all the molecules will break free and slide past each other forming a pure liquid.
if we turn off the heat the particles will lose their energy and at some point will stick to each other again forming the solid.
if we continue heating however, the molecules in the liquid will eventually break totally free and they will have enough kinetic energy to form a gas.
i hope this helped you :)
When the vacant spaces between particles of a liquid decrease, the liquid becomes more dense and its volume decreases. This can be achieved by applying pressure to the liquid or by cooling it, which causes the particles to come closer together and occupy less space.
Its the degree of attachment between the molecules of the substance: frozen (solid) the arrangement is fixed. melted (liquid) the arrangement is loose enough to be modified by gravity. evaporated: (gas) the attachment becomes insignificant.
A liquid that can turn into a solid is called a "freezing" or "solidification" process. This occurs when a liquid's temperature decreases to its freezing point, causing its particles to slow down and arrange into a more structured, solid form.
is when the solid is hard then the word is Melting to change to liquid
During the transition from a liquid to a solid, as the temperature decreases, the particles in the liquid slow down and come closer together, forming a more orderly arrangement. This results in the solidification of the substance, with the particles locked into a fixed position in a specific crystalline structure.
it depends on wether you are freezing the liquid, or melting the liquid.
This physical process is called freezing.
freezing
When you cool a liquid, the particles within the liquid lose energy and move more slowly, causing the liquid to contract and become denser. Eventually, the liquid may reach its freezing point and solidify into a solid state.
the particles are given more energy.

When a liquid is continuously cooled, its particles slow down and come closer together, eventually forming a solid. This process is called solidification or freezing.
This is a change of phase from liquid to solid.
The particles are no longer fixed by the forces keeping it a liquid
particles harden

Solid --> Liquid = melting Other changes of state: Solid --> Gas = sublimation Gas --> Solid = deposition Liquid --> Solid = freezing/solidification Gas --> Liquid = condensation Liquid --> Gas = vaporization
