Heating and cooling curve.

A heating or cooling curve is a simple line graph that shows the phase changes a given substance undergoes with increasing or decreasing temperature. They show how the temperature changes as a substance is cooled down. Just like heating curves cooling curves have horizontal flat parts where the state changes from gas to liquid or from liquid to solid. In this video we will be studying how to read and draw a heating curve.

Heating and cooling curves loading. The heating curve for carbon dioxide would have only one plateau at the sublimation temperature of co 2. The diagram shows a cooling curve for salol. The sloped areas of the graph represent a.

Steam above 100 c could be steadily cooled down to 100 c at which point it would condense to liquid water. You are likely to have used salol or stearic acid in a school practical lesson to make your own cooling curve. Notice that the temperature stays the same during the state change freezing and this is the melting point or freezing point of the salol. Hope you enjoy d i want to give a special thanks to my chemistry teac.

Cooling curves are the opposite.
