Out of tape water, distilled water, sugar water, salt water, and rain water, which will freeze the fastest?

Question

I'm doing science project and I need websites to get info from.

Answer 1

Distilled will always freeze the fastest...Since there are no impurities, distilled will freeze faster than all the others.

Answer 2

This web page tells a lot about water but does not specifically answer your question.


This page is highly detailed but again does not answer your question.

This is the best web page I found: http://chemistry.about.com/cs/howthingswork/a/aa120703a.htm

IT talks about the effect various chemicals have on the freezing point of water.

distilled water is pure and freezes at 32 degrees F. There is also many discussions about warm water freezing faster than cold water.
