  1. 1. Particles theory By Devan
  2. 2. Particles liquid solid changesMatter gas
  3. 3. Liquid is one of the three classical states of matter (the others being gas andsolid). Like a gas, a liquid is able to flow and take the shape of a container.Some liquids resist compression, while others can be compressed. Unlike agas, a liquid does not disperse to fill every space of a container, andmaintains a fairly constant density. A distinctive property of the liquid state issurface tension, leading to wetting phenomena.The density of a liquid is usually close to that of a solid, and much higherthan in a gas. Therefore, liquid and solid are both termed condensed matter.On the other hand, as liquids and gases share the ability to flow, they areboth called fluids.
  4. 4. Solid is one of the three classical states of matter.It is characterized by structural rigidity andresistance to changes of shape or volume. Unlikeliquid, a solid object does not flow to take on theshape of its container, nor does it expand to fillthe entire volume available to it like a gas does.The atoms in a solid are tightly bound to eachother.
  5. 5. Gas is 1 of the 3 basic matter form besides liquid and solid, it have noform and there is a large space between the particles so it moves freely.We can feel this matter but we cant realy touch it, this type of matter isvery useful for usThe atom arrangement should look like this
  6. 6. Is a super small thing that matter is made of. Also calledatom, particles are important in our daily life.Particle build matter that is devided into 3 basic type :solid, gas, liquidNo one really knows what does atom actualy looks likebut they illustrate it like this:
  7. 7. changes• Freezing• Melting• Sublimation• Crystallization• Vaporization• Condentation
  8. 8. freezingFreezing or solidification is a phase change in which a liquid turnsinto a solid when its temperature is lowered below its freezingpoint. The reverse process is melting.Liquid will freeze at the freezing point which is 0 degrees celcius
  9. 9. meltingA process where solid turn into liquid becauseit is heated, usualy happened in ultra hightemperature.
  10. 10. SublimationSublimation is the process of transition of asubstance from the solid phase to the gas phasewithout passing through an intermediate liquidphase (can also occur in the opposite way).
  11. 11. CrystallizationThe process of gas turning into solid withoutturning into form of liquid first (can also becalled sublimation).
  12. 12. VaporizationProcess of liquid turning into gas, there aremany factors that cause ex. Surface and heat
  13. 13. CondentationCondensation is the change of the physical state of matter fromgaseous phase into liquid phase, and is the reverse of vaporization.When the transition happens from the gaseous phase into the solidphase directly, the change is called deposition.Condensation is initiated by the formation of atomic/molecularclusters of that species within its gaseous volume—like rain drop orsnow-flake formation within clouds—or at the contact between suchgaseous phase and a (solvent) liquid or solid surface.
