States of Matter

Let's review what we learned about the states of matter.

Multiple Select

Can you remember the three states of matter? Select all three:

• Solid

• Air

• Gas

• Water

• Liquid

The three states of matter are:

• Solid

• Liquid

• Gas

Solids

Are characterized by molecules that are so close together, barely any movement is possible.

Liquids

Have molecules that are flowing freely, far enough away from each other to allow some movement.

Gases

A characterized by molecules that far apart from each other, making it easy for them to move around

Multiple Choice

What causes a change in the states of matter?

• Light

• Heat

• Pressure

Multiple Choice

Is a change in a substances states of matter a physical change or chemical change?

• Chemical

• Physical

Open Ended

In your own words, describe the difference between a chemical change and a physical change.

Remember:

A physical change alters the shape of an object without changing the chemical composition. A change in an object's chemical make-up that cannot be reversed is a chemical change.

Multiple Select

Each State of Matter is defined by how their particles behave.

¹How close the molecules are to one another, and ²how quickly they move determine what state of matter a substance is in.

Draw

Draw an example of a solid.

Solid

In a solid, particles are packed tightly together so they don't move much, but are dense. The electrons of each particle are constantly in motion, giving the atoms a small vibration, but they are fixed in their position.

​

Solids have a definite shape, as well as mass and volume, and do not conform to the shape of the container in which they are placed. 

Draw

Circle the solid.

Liquid

In a liquid, the particles are more loosely packed than in a solid, but closely enough that it is not easily compressible.

​

The particles are able to flow around each other, giving the liquid an indefinite shape. Therefore, the liquid will conform to the shape of its container.

Draw

Circle the liquid.

Gas

In a gas, the particles have a great deal of space between them, so they move easily, and have high kinetic energy (energy of movement).

Draw

Circle the gas.

Gas

​When a gas is put under pressure by reducing the volume of the container, the space between particles is reduced and the gas is compressed.

Liquid on the other hand...

In a liquid, the particles are already close together, so it is not easily compressed.

Gas

A gas has no definite shape or volume. If unconfined, the particles of a gas will spread out indefinitely (forever). However, if confined, the gas will expand to fill its container.
