C
The smallest part of an element that still has the physical properties of that element
D
The smallest part of an element that still has the chemical properties of that element
3) Why are atoms classified as matter?

Because they occupy mass and take up space
B
Because they exist in Outer Space
C
Because they are made of molecules.
D
Because they make up all living things
4) Why do the atoms of solids vibrate?
A
Because they do not have thermal energy
B
Because they have thermal energy
C
Because they attract cold air

A
A physical change produces a new substance
B
A chemical change produces a new substance
C

They have no definite shape or volume.
B
Their particles do not move at all.
C
They have a definite shape and volume
D
Their particles are much slower.
11) Through which state of matter does sound travel the slowest?
A
through solids because the particles are packed tightly together
B
through liquid because the particles are slightly spread apart and moving very slow
C
through plasma because the particles are electrically charged.
D
through air because the particles are spread very far apart and moving very fast
12) How does sound usually travel?
A
An object vibrates and those vibrations travel through the air in all directions as longitudinal waves.
B
An object vibrates and those vibrations carry air in all directions as transverse waves.
C
An object vibrates and those vibrations travel through the air in one direction as transverse waves.
