Freezing Point Depression

Freezing Point Depression


This article goes along with my first article for science fair. My project is going to be on supercooling.
As said before, supercooling is the process of water remaining as a liquid below the normal freezing point.

This is due to freezing point depression. Freezing point depression is when the freezing point of a liquid is lowered by adding a substance to it.

For example, sea water has a lower freezing point than pure water because of the added salt.

 This picture shows how the substances added to the water can hinder it from freezing.

Freezing Point Depression happens due to the number of particles present, not the amount there or the type of particles.
