CFC and HCFC refrigerants are what used to be used, also known as "freeon" but it is being outlaws because of its o-zone depleting traits. a substitute known as HFC-134a is now on the market and is being used widely.
Nitrogen is used to freeze food at a freezing temperature it is a liquid but when it hits room temperature it turns back into a gas.
A type of freon (an organic gas containing fluorine).
i believe it is furon
chloro-floro-carbons
water vapor
the temperatyre goes up
When ice is taken out of the freezer or the cold environment, it begins to melt. If the ice is keep out for an extended period of time will eventually turn into water. .
Water changes to a solid, ice, when heat is taken away from it. You can think of putting water into the freezer. Since the freezer is cold, heat flows out of the water making it become ice cubes.
No, there are no chemicals in freezer ice. Freezer ice is just frozen water, so it does not contain any additional chemicals.
My suggestion would be to find a gas that is so cold that you could freeze it upon contact. I do not have a reference chart in front of me, but you may derive a suitable and economical gas to achieve your needs. An Air Duster (used for keyboards) upside down is an example, but if this was available, why would there be no ice or freezer?
What you see is not smoke; it is mist. When you pull the ice cube tray out, a bit of air from the freezer comes with it. This air chills the room temperature air to below freezing, causing the moisture in it to form microscopic ice crystals.
Solids (ice) has a definite shape. Liquids do not have a definite shape.
the temperatyre goes up
it gets hot and melt
This is because the temperature in your freezer is higher than dry ice's sublimation point, and so it will all sublime over time. As it sublimes, the gas takes up more space than the solid, and your freezer will explode open for the gas to come out!

yes, it does, because the more you leave it in the freezer to freeze, the more time it takes to thaw out.
Ice cube shrink when left in the freezer for a long time because of the process of sublimation. This occurs when a solid mass changes directly into gas
a little bit longer because even though the freezer is cold the back is colder than the front and therefore the ice may take a while longer
of course a freezer is colder than a bowl of ice because the freezer made the ice and there are lots of frozen stuff in there.
A freezer can is the container part of an ice cream maker in which the ice cream freezes.
The answer is silo. Ice is stored in a freezer, and wheat is stored in a silo.
