States of Matter

States of Matter

Author: Anna De Leon

The students will be able to identify the three states of matter such as a liquid, solid, and gas. 

Matter is anything that has mass and takes up space. Matter is classified first by its state as a solid, liquid, or gas. All matter can move from one state to another. In this tutorial, four processes of change, melting, freezing, evaporation, and condensation, will be demonstrated to the students.

States of Matter Notes


Everything is made up of _________________________.  Matter is made up of small atoms called ____________.

All matter has ____________________ and _______________________.

Matter is classified as _____________, _____________, __________ or ____________.

Solid state

  • Has a definite _________________________.
  • Has a definite _________________________.
  • Atoms are in ______________________ positions, but vibrate each other slightly.
  • Cannot _________________________.
  • Is not _________________________.           

Liquid state

  • Has no definite ____________________. (takes the shape of its container)
  • Has a definite ____________________.
  • Atoms are free to _____________ around each other.
  • Can ___________________.
  • Is not ____________________.                    

Gas state

  • Has no definite ____________________. (takes the shape of its container)
  • Has __________ definite volume.
  • Contains atoms moving ________________ and ______________.
  • Can ____________________.
  • Can be _______________________.           


  • Matter can change from one state to another by _______________ or ______________ energy. 
  • Gaining thermal energy makes the atoms move _______________. 
  • The average speed of the atoms is measured as ____________________. 
  • If enough thermal energy is gained by a solid, it will change to a _______________ and can cause a liquid to change to a _______________.
  • Releasing thermal energy from matter causes its atoms to move _________________ and the temperature will ____________________. 
  • If enough thermal energy is released, a gas can change to a _______________ and a liquid can change to a ________________.


Changes are shown by the arrows in the diagram below.




                        SOLID                         LIQUID                          GAS



Using the diagram above, fill in the name of the process that causes the following changes in states of matter:

Change in state


solid => liquid


liquid => solid


liquid => gas


gas => liquid

The power point will reinforce the Notes that go along to describe the three states of matter.

Three States of Matter

The students will be able to identify the three states of matter such as a liquid, solid, and gas. This small lecture will reinforce the processes of the states of matter from the power point and notes.
