Solids and Liquids
In this state of matter, particles are packed tightly together and can only vibrate back and forth in place
Solid
Even though you cannot see it, this invisible mixture of gases surrounding Earth is still made of matter particles.
Air
When you stir sugar into water and it seems to vanish, it has actually broken down into particles that are this.
Too small to see.
Because particles are too small to be seen, scientists use drawings, diagrams, and simulations called this to study how they behave.
Model
In this state of matter, particles are close together but can easily slide, tumble, and flow past one another.
Liquid
This common plastic item expands and takes shape because fast-moving gas particles are constantly bouncing against its inside walls.
Balloon or ball
If you dissolve 10 grams of sugar into 100 grams of water, what will the weight of the new substance be?
110 grams
If you were drawing a particle model of a solid block of ice, you would draw the particle circles arranged like this.
tightly packed together in rows
This vocabulary term describes the building blocks that all matter is made of, which are far too tiny to see with your eyes
Particles
Unlike solids or liquids, gas particles have a lot of this between them, which allows them to easily spread out or smash together.
space
Sugar particles can hide completely inside liquid water because they slip directly into these.
Spaces between the water particles.
If you were drawing a particle model of a gas, you would draw the circles spaced out with lines or arrows to represent this.
Movement/direction/speed
This happens to the speed of particles inside liquid water when you heat it up on a stove.
They move faster
When you compress air inside a sealed syringe, the number of air particles stays exactly the same, but this happens to the spacing between them.
They get closer together
If you leave a glass of saltwater out in the sun, the water will turn to steam and vanish, leaving this behind at the bottom of the glass.
Salt
This happens to the physical volume of a balloon when it is placed in a hot car because the heated gas particles inside hit the walls harder and push outward.
It expands or gets bigger.
This state of matter has a fixed volume but changes its shape to match whatever container you pour it into.
Liquid
This is why you can smell a baking pizza across the room even though you cannot see the scent traveling through the air.
Gas particle move quickly, freely, and spread out through space
This is the phase change name given to a liquid turning into an invisible gas, separating it from any dissolved solids.
Evaporation
True or False: When a liquid water particle turns into a water vapor gas particle, the individual particle itself swells up and gets much larger.
False, (The particle size stays the same; only the space between the particles increases).
