A4.2 SAMPLES
LINKS
You cannot just have a substance - you have to have an amount of it in some form. This is called a sample.

A sample in the solid state could be in bits of any size.

A sample in the liquid state could range from a very small drop to a large volume.

The sample size does not affect the melting point.

     
a lump of salt very small grains of salt
     
a drop of water a tank of water
