page 2 – states of matter
matter exists in different forms called states. the three most common states of matter are _____________, ___________, and ___________. in a solid, particles are packed ___________ together and have a definite ___________ and ___________. in a liquid, particles are close together but can ___________ past one another. liquids have a definite ___________ but not a definite ___________. in a gas, particles move ___________ and spread out to fill all the available _____________.
matter can also change from one state to another. when a solid changes to a liquid, the process is called _____________. when a liquid changes to a gas, it is called ___________. when a gas cools and turns into a liquid, the process is called ___________. when a liquid turns into a solid, it is called _____________.
the temperature at which a solid becomes a liquid is called the _____________ point, while the temperature at which a liquid becomes a gas is called the _____________ point.

Explanation:

Answer:

The three most common states of matter are solid, liquid, and gas. In a solid, particles are packed tightly together and have a definite shape and volume. In a liquid, particles are close together but can slide past one another. Liquids have a definite volume but not a definite shape. In a gas, particles move freely and spread out to fill all the available space.
When a solid changes to a liquid, the process is called melting. When a liquid changes to a gas, it is called evaporation (or boiling). When a gas cools and turns into a liquid, the process is called condensation. When a liquid turns into a solid, it is called freezing.
The temperature at which a solid becomes a liquid is called the melting point, while the temperature at which a liquid becomes a gas is called the boiling point.
