Describe the substance between letters a and b.
Heating and cooling curve graph.
The diagram shows a cooling curve for salol.
A heating or cooling curve is a simple line graph that shows the phase changes a given substance undergoes with increasing or decreasing temperature.
In this video i will explain the concept of heating and cooling curves as they applies to water and ethanol.
Just like heating curves cooling curves have horizontal flat parts where the state changes from gas to liquid or from liquid to solid.
They show how the temperature changes as a substance is cooled down.
Notice that the temperature stays the same during the state change freezing and this is the melting point.
Linked to the particles topic showing heating cooling curves for substances.
Heating curve of water the phase transitions of water.
Cooling curves are the opposite.
Https www freesciencelessons co uk workbooks in this video we look at heating and cooling curves.
