Matter Vocabulary
This is the smallest piece of an element that still has all the properties of that element.
an atom
In this state of matter the molecules are strongly attracted to each other and only vibrate.
a solid
Molecules move more freely when you do this.
add heat or energy
This does not affect the independent properties of matter.
changing size
This is the amount of matter in something.
mass
This is made when atoms join together.
a molecule
In this state of matter the molecules are weakly attracted to each other and move freely to fill the entire space of their container.
a gas
Molecules move less when you do this.
remove heat or energy
This describes how tightly packed matter is.
density
This is the amount of space something takes up. (Its size)
volume
This is a pure substance made of only one kind of atom.
an element
In this state of matter the molecules are not as strongly attracted to each other and can move easily around each other.
a liquid
This is what happens to the distance between molecules when you remove heat.
the distance decreases (molecules are closer together)
This describes how well one substance will dissolve in another substance.
solubility
This is a measure of the force of gravity on an object.
weight
This is a homogeneous mixture where the concentration of materials is the same throughout.
a solution
The speed of molecules does this as you move from a solid to a liquid to a gas.
increase (move faster)
This is what happens to the distance between molecules when you add heat.
distance increases (molecules are farther apart)
This is the temperature at which 50 L and 100 L of water will begin to freeze.
0 degrees Celsius or 32 degrees Fahrenheit
This tool can be used to find the volume of liquids and oddly shaped solids.
a graduated cylinder
This is a heterogeneous combination of materials; the concentration of materials is not the same throughout.
a mixture
This is what happens to the attraction of molecules as you move from a solid to a liquid to a gas.
they become less attracted to each other
The density of matter will do this as you add heat or energy.
decrease (the matter will be less dense)
This is the substance that is put into a solvent.
solute
This tool can be used to find the mass of objects by moving weights to balance the mass of the object.
a triple beam balance
