Solids, Liquids and Gases
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.
