[DVBC] Physics question

[Pazos, Javier]

Your chemistry teacher was wrong.  The reason warm or hot water FROM THE FAUCET freezes faster is because impurities in suspension settle out while it is in the hot water heater.  You can achieve the same effect by using filtered water (test it-you'll see).  

Many things could have contributed to Bob's bottle freezing faster.  It could have been the geometry of the bottle, the material the bottle was made of, the materials that the bike and bottle cages are made of, etc.  It could also be because of impurities.

Tom is absolutely right that adding Gatorade will slow the freezing.  Brandy will also work-at least that's what the St. Bernards tell me.

As Cliff Claven would have said "Its a little known fact Normie" warm water 
freezes faster than cold water because the warm water has less oxygen 
content. At least that's what I learned in Chemistry class. The best way to 
slow freezing is to add a little sodium (Gatorade) as this will lower the 
freezing point of the water.
