Solids

Solids have a definite shape and a definite volume

Their shape remains the same no matter what container they are in.

Draw what you see at the table. Write or draw your own example

of a solid.

Liquids Liquids have a definite volume,

but no shape of their own. They take the shape of their

container. Draw what you see at the table:

each container contains 1 liter of liquid.

Write or draw your own example of a liquid.

Gases

Gases have no definite volume or shape.

They fill and take the shape of their container.

Draw what you see at the table. Write or draw your own example

of a gas.

Freezing Freezing is the change in state

from a liquid to a solid. Does energy need to be added or

taken away from a liquid to make a solid?

Basalt is frozen, ice is frozen, but wood is not. Why do you think that is?

Draw what you see at the table. Write or draw your own example

of freezing.

Vaporization (boiling)

Boiling is the change in state from a liquid to a gas at the boiling point of the liquid.

Does energy need to be added or taken away from a liquid to make a gas?

The boiling point for water is 100oC.

Draw what you see at the table. Write or draw your own example

of boiling.

Condensation Condensation is the change in state

from a gas to a liquid. What do you notice about the outside

surface of the container? Where is the gas coming from for this

liquid? Does energy need to be added or taken

away from a gas to make a liquid? Draw what you see at this table. Write or draw your own example of

condensation.

Melting

Melting is the change in state from a solid to a liquid.

Does energy need to be added or taken away from a solid to make a liquid?

Draw what you see at the table. Write or draw your own example

of melting.

Vaporization (evaporation)

Evaporation is the change from a liquid to a gas, below the boiling point of the liquid.

Use one of the alcohol swabs to wipe back the back of your hand.

Describe how your hand feels as the alcohol evaporates - hot or cool?

Does energy need to be added or taken away from a liquid to make a gas?

Write or draw your own example of evaporation

Sublimation

DON’T TOUCH anything on this tray.

Sublimation is the change in state of a solid into a gas, without going through the liquid state.

Does energy need to be added or taken away from a solid to make a gas?
