Basics of Matter
What is the definition of matter?
The state of matter that is rigid and has a fixed shape and volume.
solid
This process happens when a liquid turns into a gas, like a wet shirt drying.
evaporation
Cutting a piece of wood into smaller pieces is this type of change.
physical change
These are materials found in our environment that are used to make other things, like wood from a tree.
raw materials
Matter is made up of these tiny constantly moving particles.
atoms
This state of matter has a fixed volume but takes the shape of its container.
liquid
This state of matter has no fixed shape or volume and can be easily compressed.
gas
chemical change
This property describes a material's ability to let water in, like a sponge or a towel.
being absorbent
These are the three common states of matter found on Earth.
solid, liquid, gas
In this state particles are held tightly together and only vibrate instead of moving around.
solid
This is the process of a has turning back into a liquid, often seen as droplets on a cold glass.
condensation
Name two of the five signs that a chemical change has occurred.
There is a change in color, a new smell, gas bubbles, temperature change, or the formation of a new solid.
This is the opposite of absorbing, it is the ability of a material, like a rain jacket or rubber boots, to keep water away.
repelling
These two things are mistaken for matter, but they are actually energy.
Materials like sponges have this property, while wood and stone generally do not.
Being absorbent (or the ability to absorb)
This rare process occurs when a solid turns directly into a gas without melting first.
sublimation
chemical change
plant, animal or mined materials
Are the particles further apart in a solid or gas.
gas
This term describes the ability of an object to float in fluid.
buoyancy
Air is considered matter because it has these two properties, which can be proven by blowing up a balloon.
It has weight (mass) and takes up space (volume).
Freezing water into ice is what kind of change?
physical change
What is a raw resource that is commonly used for building?
wood
