3. Liquid is one of the three classical states of matter (the others being gas and
solid). 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 a
gas, a liquid does not disperse to fill every space of a container, and
maintains a fairly constant density. A distinctive property of the liquid state is
surface tension, leading to wetting phenomena.
The density of a liquid is usually close to that of a solid, and much higher
than 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 are
both called fluids.

4. Solid is one of the three classical states of matter.
It is characterized by structural rigidity and
resistance to changes of shape or volume. Unlike
liquid, a solid object does not flow to take on the
shape of its container, nor does it expand to fill
the entire volume available to it like a gas does.
The atoms in a solid are tightly bound to each
other.

5. Gas is 1 of the 3 basic matter form besides liquid and solid, it have no
form 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 is
very useful for us
The atom arrangement should look like this

6. Is a super small thing that matter is made of. Also called
atom, particles are important in our daily life.
Particle build matter that is devided into 3 basic type :
solid, gas, liquid
No one really knows what does atom actualy looks like
but they illustrate it like this:

7. changes
• Freezing
• Melting
• Sublimation
• Crystallization
• Vaporization
• Condentation

8. freezing
Freezing or solidification is a phase change in which a liquid turns
into a solid when its temperature is lowered below its freezing
point. The reverse process is melting.
Liquid will freeze at the freezing point which is 0 degrees celcius

9. melting
A process where solid turn into liquid because
it is heated, usualy happened in ultra high
temperature.

10. Sublimation
Sublimation is the process of transition of a
substance from the solid phase to the gas phase
without passing through an intermediate liquid
phase (can also occur in the opposite way).

11. Crystallization
The process of gas turning into solid without
turning into form of liquid first (can also be
called sublimation).

12. Vaporization
Process of liquid turning into gas, there are
many factors that cause ex. Surface and heat

13. Condentation
Condensation is the change of the physical state of matter from
gaseous phase into liquid phase, and is the reverse of vaporization.
When the transition happens from the gaseous phase into the solid
phase directly, the change is called deposition.
Condensation is initiated by the formation of atomic/molecular
clusters of that species within its gaseous volume—like rain drop or
snow-flake formation within clouds—or at the contact between such
gaseous phase and a (solvent) liquid or solid surface.
