Liquids have a definite ________ but not a definite _________.
volume, shape. The amount stays the same, but it can flow into different containers or shapes.

Gases have no definite ______ or _______. They go in every direction to fill the container they are in.
shape or volume

When a liquid gets cooled and loses heat, it becomes a _________. (liquid - heat = _____)
solid

What do we call the phase change of a solid turning into a liquid? Example - fruit popsicle turns to fruit juice
melting

True or False: Solids can change their shape easily.
false - they do not change shape unless bent or broken
200
How can liquids change their shape?
Flowing into a new container

List 3 liquids you might use in your day.
water, milk, apple juice, orange juice, soap, hand sanitizer, glue, syrup, etc.
300
List at least 2 types of gas you know of.
perfume, steam/water vapor, helium in a balloon, oxygen, etc.
300
When heat is added to a liquid, it becomes _______. (liquid + heat = ____)
gas
300
What do we call the change of a liquid turning into a gas? Example - water puddle turns into water vapor in the clouds
evaporation
400
Are the particles of a solid far apart, close by, or tight together?
tight together and can't move much
400
If I take a small carton of milk from the cafeteria and pour all of it into a big bowl, which one has more milk? The small carton or the big bowl?
They both have the same amount. The volume stays the same, but the container or shape can change.
400
Can a gas keep a shape?
Only if the container has a lid, the gas spreads to fill the container. If it has no lid, the gas escapes and goes everywhere - so no it would not keep a shape.
400
When heat is added to a solid, it turns into _____. (solid + heat = ______)
liquid
400
______ is the change of a gas turning into a liquid? Example - air vapor in clouds turn into rain
condensation
500
Draw what the particles of a solid look like.
Particles are tight together, not able to move much because they are so close.
500
Draw what the particles in a liquid look like.
Particles are near by but still have some space to move about easily.
500
Draw what the particles in gas look like.
Particles in gas are spread far apart so they can move easily. They move extremely fast and can bounce off one another.
500
What has to happen for matter to change states?
Heat must be added to or taken from it.
500
____________ is the change of a solid turning to a gas. Example - Dry ice on the counter turns into water vapor in the air
sublimation
