Safety First!
First add the
air freshener
to a cup
Add the
cardboard to
the cup.
Add the
second cup
over the first
but make
sure that
the second
cup doesn’t
touch the
air freshener.
Add ice to
the top cup
but make sure
no ice or
water touches
the freshener
Fill the
container
up with
hot tap
water.

Observe what
happens!

 1 Sublimation is the change of substance from a solid to a
vapor without having to pass through the liquid state.
 2 I have came to a clear understanding that the solids in the
experiment were sitting in room temperature water it wouldn’t
have worked. The process would have not been able to skip the
liquid state in order to change state. If the water was in boiling
water I understand that the solid will go directly from solid state
to a gaseous state. When cooled it goes from gaseous to solid.
 3 The temperatures will affect the states in the transformation
from a solid to vapor pressure. This can be done by the exceed
atmospheric pressure.
