Your right i shouldn't take one guys attempt at being a smart ***, as a scale of the intelligence of people on NAM.

You got me there anyone who has or does look at buying a mini must be somewhat intelligent.


Your right it does happen a lot without extrordinary high or low pressure, But in relation to water it does, or atleast from what i have seen and read take pressure.

 

Isn't sublimation the band that guy was in that OD'd on heroin

 

Is there a way to disable that annoying ice warning chime sound? Being in a heated garage, it can take a while after I exit the garage until the thermometer registers the true outside temperature. So I often hear the chime in the middle of my drive, proving to be extremely distracting and annoying. And being in a Canadian winter, I don't need to be reminded EVERY day that the temperature is below freezing. Any way to disable it?

 

No, water will sublimate even at normal atmospheric pressure. Just look at an ice cube in your freezer that's fallen out of the ice cube tray and laid there for a while. The edges will be rounded off, and over time it will shrink and disappear entirely, all without ever having entered a liquid state. As long as the vapor pressure of ice is greater than zero and the temperature is less than freezing, ice will sublimate (and the vapor pressure of ice is still greater than zero all the down to below -60F).

 

That is funny.

 

i thought sublimation was how you were supposed to deal with all of your carnal desires.

 

I do not know why I am getting involved in this discussion but...
Sublimation is the process whereby a substance passes from solid to a gas, without going thru a liquid state. The best example is "dry ice" or CO2 which people are familiar with. Ice can do this under certain conditions such as the previously mentioned ice in the freezer but the cause there is because the air in the freezer has a very low humidity (Boyles law of partial pressure I think)
Water in fact does not necessarily freeze @ 32 degrees. If you could measure the temp of a unit of water @ 40 degrees and then follow its temp down to say 30 degrees you would see that it drops to 32 degrees at a steady rate. Upon reaching 32 degrees, it would stay at 32 degrees until it loses a certain amount of heat and then turns to ice and drops at a steady rate once more. This pause in the heat loss or gain between transition from a liquid to a gas is called the heat of vaporization. See that college chemistry class was not the total waste I thought it was. I promise I will remain silent in the future.

 

I rather hear a chime in a car or elevator, for that mater, that warns passengers of stealthy sublimation, giving you time to crack the windows or hit all the elevator buttons

 

Heck no! "Chime in" with the rest of us...I think you could actually hold your own in any thread.

 

Back to the original question: I was under the impression that the temp flashing and alarm were to tell you that the mirror and headlight washer heaters were on (when equipped with the cold weather package).

 

That may be the case for the people with the cold weather package, But for the rest of us it does this at 37 and below to let you know that there could be ice on the road.

 

I love when it does that! I don't hear it too much living in Cali.

 

The mirror and windshield (not headlight) washer heaters are not temperature activated, and are on all the time whenever the engine is running. It's in the owner's manual.
