It decreases. In gaseous phase the molecules are further apart than they are in the solid phase so although in solid phase the molecules are still moving minimally they haven't got the space to move around in that they would in the gaseous phase.
It turns to a solid.
This phenomenon is called sublimation.
it increases
it turns to boiling hot molten golddummy
it hardens but based on matter it is still a solid
the particles move and they shift into a blob. or the liquid is frozen
It is from the liquid phase to the solid phase. It is called freezing.
The gas can't generally turn straight into a solid, it has to change into a liquid and then a solid. When a gas turns into a liquid, the particles go closer together into groups and condensate. When the liquid turns into a solid, the particles all compress into a small space thus making a solid object.-----------------------------------------------------------------------But the phenomenon of change from a gas to a solid is also very known and is called deposition.
When a liquid is cooled, it turns back into a solid through the process of solidification. This is because cooling reduces the kinetic energy of the particles, causing them to move closer together and form a solid structure.
Water turns to solid when it freezes.
It turns into a solid because of the loss of kinetic energy. The particles of the substance slow way down and barely move, other than vibrating in place.
When a solid turns into a liquid, the substance has melted.
