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?
