The entire experiment could be run in reverse.
Heating and cooling curve.
Steam above 100 c could be steadily cooled down to 100 c at which point it would condense to liquid water.
The heating curve for carbon dioxide would have only one plateau at the sublimation temperature of co 2.
Cooling curves are the opposite.
Just like heating curves cooling curves have horizontal flat parts where the state changes from gas to liquid or from liquid to solid.
Heating and cooling curves loading.
They show how the temperature changes as a substance is cooled down.
Color highlighted text notes.
You are likely to have used salol or stearic acid in a school practical lesson to make your own cooling curve.
Found a content error.
Notice that the temperature stays the same during the state change freezing and this is the melting point or freezing point of the salol.

The diagram shows a cooling curve for salol.
