​An element is a substance composed of only one type of atom.

​Atomic number

All atoms have smaller parts called subatomic particles: protons, neutrons, and ectrons.
The number of protons an atom has is called its atomic number.

​States of matter

States refers to the forms in which matter can exist.
There are 3 main states of matter: solids, liquids, and gases.

Multiple Choice

When heat energy is added to a liquid, its particles move faster and changes from liquid state to becomes gas. This is called ---------.

• vaporization

• freezing

• melting

The boiling point of a substance will not change based on how much of the substance you have.

Boiling point

Multiple Choice

Sam has two blocks that are the same size.  One block is much heavier than the other block.  What statement is true about the blocks based on this information?

• They have different densities.

• They have different boiling point

Multiple Choice

When particles in a gas lose heat energy and move closer together, the substance becomes a liquid. This is called ----------.

• condensation

• evaporation

• melting

Multiple Choice

If the substance continues to lose heat energy, it may eventually become a solid. This is called --------.

• freezing

• boiling

• melting

The freezing point of a substance is the temperature at which it changes from its liquid state to its solid state.
It is the same temperature as the melting point.

​Freezing point

The melting point of a substance is the temperature at which it changes from its solid state to its liquid state. For water, the melting point is 0° Celsius or 32° Fahrenheit.
