Comparing solids,liquids,and gases g3

Ch.11, Lesson 2(comparing solids, Liquids and Gases)

How can you classify Matter?

There are 3 states of matter

Vocabulary:SolidLiquidGasPhysical changeMixtureSolutionObjectives:1- Identify and differentiate between solids, liquid and gases2-defferntiate between physical change and chemical change.

2


Is matter that has a definite size and shape.

Definite= it stays the same.

If you put it in a jar or a box, it stays the same.


3

Solid


Is matter that has a definite volume.

It doesn’t have a definite shape If you pour juice into a glass, it will take on the shape of glass.


4

Liquid


Is matter that has no definite shape or volume.

Gas takes the shape of whatever container they are in.

The air all around us is a gas.


5

Gas


Matter is made of particles.

Particles are very, very small.

In Solids particles are packed closely together, so they form a certain pattern.

In Liquids particles are close together but don’t form a pattern.

They have more energy and can slide past one another.

In Gas particles have more energy, they spread out to fill a large container, or squeeze together to fit into a small one.

How can Matter change?

Matter can change but still remain the same kind of matter.

* If you cut a paper, it will look different but still made of the same particles.

* If you cut and sand the wood to make a wooden model, its shape and size change but it is still wood.


9


Is a change in how the matter looks, but not in the kind of matter it is.

Ex. Cutting, bending, sifting, sanding and pounding.


10

Physical change


Matter can also change in state.

We can find water in the solid, liquid, or gas state.

Water looks different in each state but it is still the same kind of matter.


11


Ice is the solid state…..particles are close together, they don’t move very much.

When ice is heated …..it melts, so change from solid to liquidstate…..particles have more energy and move faster.

When water is heated….it evaporates, change from liquid to gas state and called water vapor.

12


When water vapor cools….it looses energy and condenses…..it becomes liquid.

When liquid water cools, it freezes into ice.

Melting, evaporating, condensing, and freezing are examples of physical changes.


13


Can you mix different kinds of matter together?

When you mix different kinds of matter together.

In a mixture the properties of each kind of matter don’t change.

Ex. Fruit salad is a mixture of many kinds of fruit, if you pick out a piece of orange it will look like any orange piece.


14

Mixture


Mixture can be combination of solids, liquids, and gases.

Air is a mixture of different gases.


15


What is a solution?

Is a kind of mixture.

It forms when one or more kinds of matter are mixed evenly in another kind of matter.

It is a physical change.

Ex. Salt water, if you mix salt with water….you can’t see the salt anymore.


16

Solution


If the water evaporates , the salt will be left behind.

Not all solids form solutions in water.

If you mix sand with water….the sand will just sink in the bottom.


17


Some solutions have no liquids.

Ex. Air is a solution of different gases.

Ex. Steel is a solution of several solids, it is used to make cars, bridges, and buildings.
