Different substances freeze differently. But for your purposes, compare water to salt water. The salt in the water causes there to be more things in the water that disrupt the tight hydrogen bonds.Since freezing is tighter H-bonds, salt lowers the freezing temperature because it is harder to freeze it now since there is salt in it.
