Solids, Liquids and Gases

FROZEN SOLIDS

Fruit frozen in the solid. The fruit is unable to

move.

Pouring liquid into the popsicle model. The liquid takes the

shape of the model, but when frozen keeps the shape.

Popsicle keeps its shape as long as frozen SOLID, but when it melts to

become a LIQUID it takes the shape of

the glass.

Liquids take the shape of their container.

Fish can swim through the water. The cat can put

his paw through the water and walk through the air.

The water in the fish bowl will take the shape of the

fish bowl, however the fish does not change its shape

in a different bowl.

The cat can also swim through the liquid water

The helium gas takes the shape of

the balloon

Solid Liquid Gas

observation

Keep their shape

Cannot put hand through

Ex. Choc. bunny, ice sculptures, popsicles, fish

Takes shape of container

Ex. Water in fish bowl

Round or head-shaped

Can put hand through

Takes shape of container

Ex. Balloons gas takes shape of balloon

FREEDOM OF MOVEMENT

So the particles

Particles must stay in fixed positions (same place or locked in place)

Cannot move to a new spot

Particles must be free to move to a new location. They can move to new spot in new shape.

Particles move to new spots to take the collection takes the shape of the container.

Observation- compression

Cannot be compressed

Volume stays the same

Cannot be compressed

Water in the syringe could not push it down

Can be compressed

We could squish it and make it smaller

SPACING OF PARTICLES

So the particles

Particles must be as close as they can get.

We cannot push them any closer

Since we cannot push the particles any closer, the particles must already be as close as they can get

So we must have pushed the particles closer together. The particles must have been far apart.
