The recommended temperature for a freezer is between -18 and -20 C. The ice will get down to this temperature.

I used to think, anywhere below 0C was all that was needed but only in the last 5 years I found that freezer should be a lot colder than that for storage of food. Maybe something to do with "water" freezes at 0C but other substances a different temperature is required, fish notably. So maybe the answer is -15, -20C. Or, as someone stated, whatever the thermostat is set to.

My guess would be 32 F or 0 c. I base this on the fact that to set a thermometer you insert it in a glass of ice and cold water. The set point should go to 32 F. If it were vastly colder than that it would skew the reading of the thermometer and you would not be able to accurately adjust it.

My LG refrigerator shows the temperature on the door. I recall it's usually 0°F

OK no Google just thought.
Water freezes at 32 deg. F thereby forming ice.
When ice is moved to room temperature it begins to melt turning back into water.
Even if water was frozen to "Absolute Zero" (-459.67 Deg F) It does not stay colder any longer in room temperature.
Therefore my answer is 32 Deg. F

The many replies saying the ice will get to 0C and not any colder are all mistaken. Water, once fully frozen, will behave like any other solid and will go down in temperature to that of its surroundings, i.e. the -20C or so of the freezer. The only two times that water, or any other substance, will stay at one temperature when heat is added or subtracted is the two transition points, i.e. changing from solid to liquid or back (0C) or to steam or back (100C), both temperatures being standard atmospheric pressure.
So I will back my earlier reply as the valid one, i.e. the ice will get down to the temperature of the freezer, normally about -18C to -20C.

You're right. The freezer temp is typically 0F or -18C like you said.

Very good my friends. I mistakenly have always thought that 0 degrees C or 32 Fahrenheit was the temperature of freezing water but alas it will cool down to the temperature of the freezer. Apparently if you record the cooling temperature of water in a freezer it will cool to freezing point and then remain there for some time before the temperature drops further. This stage is due to the energy being used to slow the molecules down as the ice is formed. Another thing learned - now on to problem 4......

Ice cream is kept colder -20F in grocery stores and will take longer to warm up which makes it take longer to thaw during the trip home. At this temperature it is as hard as a rock. All thinks solid liquid or gas will adjust to whatever temperature they are subjected to.

At 0ºF, "ice cream" is almost rock hard. I microwave a full half gallon for 25 seconds to facilitate eating. As the volume decreases, I reduce that time accordingly. Yes, home freezers are set to 0º F.
