3. Definition Change of Objects Shape
Under certain conditions a substance, namely solid, liquid, and gas
cannot maintain its shape. That is why it can experience changes in form
such as changing color, changing shape, and smells or other odors
appear from its previous form. This happens, of course, not without
cause, but because the substance is under certain conditions which are
affected by heat, temperature, humidity, and so on.
5. -Have a shape that tends to remain even though it is
placed in a certain place, even tends to be the same
even though it is moved to a different place
- Not easy to change shape
-To change the shape of a solid object usually
requires a fairly long process with various kinds of
effort, such as hitting, pressing, and so on.
Solids
7. -The shape is not fixed and will adjust to the shape of the container
that holds it
-It is flowing or easy to move from a higher place to a lower place
because of the law of gravity
- Liquids can seep into the small cracks or pores of a surface, such
as soil, paper, tissue, cloth, sponges, and so on
-Have pressure to go in any direction
-Have a surface that is always flat in any container shape
conditions
-Have a wave motion that can be affected by several factors, such
as wind and thrust
Liquids
9. -Have a shape and volume that adjusts to the shape
or condition of the container that holds it. That is
why the shape of the gas will depend on the shape
and condition of the container.
-In addition, the volume of air will also depend
heavily on the contents and volume of the container.
-Has pressure that can press in all directions.
Gases
10. Objects in Everyday Life
Can you identify which Solids, Liquids, and Gases objetcs?
12. Ice (Solid) Water (Liquid)
• Melting
Melting is a form of change of state that occurs in a solid to a
liquid. Adding (heating) or removing heat (cooling) from an object
can change its state of matter.
13. Ice (Solid)
Water (Liquid)
2. Freezing
Freezing is a form of change in state that occurs in liquid objects into
solid objects. The change in state of freezing is practically the
opposite of melting. Freeze water in the freezer into ice cubes
14. 3. Evaporating
Evaporation is a form of change of state that occurs in a liquid to
become a gas. Evaporation is a change of state that requires heat or
heating.
What we see most often is
when boiling water, when it
boils it will release steam.
15. 4. Condensing
Condensation is a form of change of state that occurs in a gas object
into a liquid object. Condensation occurs in gases in cold air or low
temperatures into water droplets.
16. 5. Sublimation
Sublimation is a form of change in form that occurs in solid objects
into gaseous materials. The process of changing form by sublimation
requires heat or heat energy so that the solid object can turn into
gas molecules in the air.
17. Crystallization is a form of change in state that occurs in gaseous materials into
denser materials. The process of changing this form occurs due to the release of
heat energy or heat at a lower temperature than the object.
