does a substance get colder when its freezing?

I can't vote yet (hopefully by next week if all goes well), but Amy F has the correct answer. All of these peeps that are telling you that substances do get colder are wrong. A substance does not gain or lose any heat during the actual process of freezing (or melting, or boiling for that matter).
Update -----
I can give thumbs up!! (and thumbs down :))

No, during the process of freezing the substance stays exactly at its freezing point. All energy lost is lost in the form of entropy as the substance becomes more ordered and loses the ability to move. It doesn't start getting colder again until it's all the way frozen.

If a substance is getting colder it means that it is going through an exothermic process. When something is exothermic it means that it is releasing energy into its surroundings. As it loses energy the particles in the substance move slower and slower. As the particles slow down the substance becomes more solid. Even when the solid freezes the particles in it are still vibrating. Particles only stop moving completely at absolute zero. So, as a substance freezes the particles move more slowly and release energy (heat) so they have less heat in them. A substance can freeze without losing heat though. For example, you can boil water at room temperature by lowering the pressure and after boiling for awhile and releasing all of its energy it will freeze at room temperature.

yes, a substance gets colder when it freezes. freezes means that the substance is releasing energy which is another way of saying "getting colder"

The reason a substance is freezing is because it is getting cooler - the particles move slower as it cools down, eventually getting to the point when they are barely moving (always moving though). That's when a substance solidifies - or freezes - or becomes a solid :)

obviously but not with all substances I'm sure there are some odd balls but yes generally when a substance is frozen its temperature decreases whether metal or mineral
