Now that we've managed to merge cold weather and alcohol into a single message thread, I'm reminded of my college days when we would go outside in sub-freezing weather with a bottle of beer. The beer would be liquid when you opened and for that first sip or two. But by the third or fourth sip, it would be a semi-frozen beer slushie! It happened way to fast to just be ambient cooling. The combination of expansion due to pressure relief and outgassing of the dissolved carbon dioxide simultaneously cooled the drink as well as raised the freezing point. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Douglas O.

Up in these parts of the Midwest, especially Wisconsin, there is a winter libation called Brandy Slush. Make the recipe with 1 cup of brandy, it freezes in an a few hours. Make it with 2 cups of brandy, it freezes in 3 days. Make it with 3 cups (or more) and it does not freeze. Thought I would pass this valuable bit of chemistry on.

According to CRC Handbook of Chemistry and Pysics, if you do what you describe the sucrose solution will have a freezing point depression of 4.93C, the Ethylene glycol 38.81C and the Calcium chloride 49.7C. Now I would have said that the sucrose would freeze first because it has a concentration of 1.5M, the Calcium chloride next at 4.5M and then the Ethylene glycol at 8.0M. But the difference must be because of dissolved solids. -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Precision Analytical Lab Sent: Friday, March 18, 2005 3:34 PM To: [log in to unmask] Subject: Re: [TN] Answer to Friday's question It has to do with the total number of particles in solution. In this case, the smaller the number, the faster it freezes..and vice versa. I begin with the same weight of material, 10 grams, but I have to take each formula weight into account as well. Popsicles also have other ingredients, such as flavorings, etc. Anti-freeze has methanol along with the glycol to help lower it's freezing point. -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Bill Kasprzak Sent: Friday, March 18, 2005 3:17 PM To: [log in to unmask] Subject: Re: [TN] Answer to Friday's question I disagree. Why do Popsicle's stay frozen in my freezer while the anti freeze in my car is protects my car to 20 below F. Certainly my freezer doesn't go to 30 below F. Now I know why I'll get a bloody nose.

So, the original question was a tad bit on the devious side. However, if you did use enough DI water to completely dissolve each of those materials, they will begin to freeze in this order: First to begin freezing is the ethylene glycol (antifreeze), second will be the calcium chloride (Indiana's road salt), and last is the sucrose (sugar).

Its Friday and I am not less than 5 hours ahead of all you guys and now I will have to spend the entire week-end wondering about the true answer. My shot will be Calcium Chloride time because of the De-ionised water, then sucrose unless the water is hot, then the diluted anti-freeze. I haven't a clue as to why, just gut feeling. -- Regards Graham Naisbitt [log in to unmask] Golf quote of the week: If you watch a game, it's fun. If you play it, it's recreation.
