Yes the air in the freezer will lower the temperature of anything stored in it till it reaches the same and keep it there providing the freezer is in good working order.
If you mean the temperature inside a freezer, these are usually around -18 to -19 degrees celsius or 0 to -2 degrees Fahrenheit
A commerical freezer temperature can be set to 0 degrees to negative 40 degrees Celcius ( oC to -40C).
0 degrees is ideal.
The best freezer temperature for meat is 30 degrees Fahrenheit. Home freezers are meant to be 32 degrees maximum.
0°C = 32°F 0°F = -17.8°C (about the same temperature as a home freezer)
Water freezes at 0 degrees Celsius. This is equal to 0 x 9 = 0 / 5 = 0 + 32 = 32 degrees Fahrenheit.
as fast it can get to 0 degrees you have to more specific.
Keep your freezer at zero degrees (0°) or below to maintain the quality of frozen foods. Most foods will maintain good quality longer if the freezer temperature is -10 to -20°F. At temperatures between 0 and 32°F, food deteriorates more rapidly.
Seal the food in an airtight container or with freezer wrap and place it in the freezer. The best temperatures for long-term freezing of foods is between 0 degrees F to -18 degrees F, depending on the length you plan to leave the food in the freezer.
Ice will only form from water once water is cooled to below 0 degrees Centigrade. A freezer requires energy (ie it needs to be turned on) in order to pump heat out of the freezing compartment to lower the temperature in this compartment to below 0 degrees Centigrade. If the freezer is not turned on the temperature in the freezing compartment will be that of the room in which the freezer is kept.
at least -18 degrees
Place the water in an area that has a temperature of under 0 degrees Celsius. A freezer will do.
