Which state of matter has particles that vibrate in a fixed position?
Solids
Why can't particles be seen with the human eye?
They're too small.
An ___ is the smallest part of an element that is still that element
Atom
Why is a balloon with air in it heavier than a balloon without air?
It contains matter.
A __________ is made of two or more atoms
connected or bonded together.
molecule
Which state of matter has weak or no attraction between the molecules?
Gas
If you could use a powerful microscope to see the particles in a gas, what would you see between the particles?
Empty Space
A _____ is a characteristic of a substance or element that is always true.
Property
Can some elements share all properties? Why?
No because if they shared all of the same properties they would be the same
Heating a gas easily increases the
_______ of the gas particles.
Volume
True or False: The volume of solids cannot be changed due to the strong attraction of the particles.
True
A basket ball deflates in the cold because particles of matter.....
move closer together and take up less space
Something that is made up of either one type of atom or one type of molecule all the way through
Substance

Gas, liquid, solid
_____________can affect how far apart or close together the molecules in a substance are.
Temperature
True
How does temperature change the speed of particles?
When the temperature increases so does the speed of the particles
When the temperature decreases so does the speed of the particles
Made up of the same type of atom all the way through
