Melting and freezing curve of



Principle

How does a temperature curve express the change of state of a substance that occurs when it is heated or cooled? The students are heating sodium thiosulphate until it melts and let it cool down again. They measure the behaviour of the temperature
in dependence on time under uniform heat input or output.
