d) The smallest part of an element that does not have the chemical or physical properties of that element.
Why are atoms classified as matter?
a) Because they are made of molecules.
b) Because they make up all living things
c) Because they occupy mass and take up space
d) Because they exist in Outer Space
Why do the atoms of solids vibrate?

How is a chemical change different from a physical change?
a) A chemical change produces a new substance
b) A physical change produces a new substance

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