Materials:-Small Pieces of Air Freshener-Small Shallow Container-2 Clear 8 oz plastic Cups-Hot Tap Water-Ice-3 thick cardboard Strips

Safety First!

First add theair freshener to a cup

Add the cardboard to

the cup.

Add the second cupover the firstbut makesure thatthe secondcup doesn’t touch theair freshener.

Add ice tothe top cup

but make sureno ice or

water touchesthe freshener

Fill thecontainerup withhot tapwater.About1/3 full

Observe whathappens!

Analyze 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.
