It takes a lot of energy to melt ice. For water to turn into ice this energy has to leave the water so if the air temperature is just below freezing it takes some time for this energy to leave the water.
Water is also unusual because it becomes less dense as it freezes. Most solids are more dense than the liquid they are formed from, this means they sink. Ice is less dense than water just above the freezing point. This means ice floats. For a lake this is significant. The ice forms on top of the water providing some insulation for the water underneath. If it snows this is even more significant because snow is quite a good insulator due to the trapped air inside it. Rather than the snow falling into the water and cooling the water as it melts it sits on top of the ice and adds an insulating layer.
water doesn't take long to freeze in a freezer. It has always taken that long to freeze. Chill out man/women
The freezer is kept colder than the fridge. Mine says recommended temp for freezer is 0°F and 37°F for fridge.
it depends on what's the temperature you freeze it in. if you freeze it in a freezer with the temperature at 5 degrees it might take about 45 minutes to an hour.
water freezes faster and only water freezes it takes AGES for salt water to freeze water takes about 4 hours in a freezer
It depends on how you're trying to freeze them, of course: if you have a freezer that goes to 0 degrees F, like the one in the back room of a supermarket, it'll take as long to freeze the salt water as it would plain water. (Salt water has a lower freezing temperature than plain water but if you have a cold-enough freezer, it'll freeze.) If you pour it into liquid nitrogen, it'll freeze instantly. It also depends on the temperature of the salt water at first. Also, which type of salt, and how pure the water is. It also depends on the concentration of salt.
There is no standard length of time that it takes for a gallon of water to freeze. The amount of time it takes for a gallon of water to freeze can vary depending upon many different things such as temperature.
That would depend on the amount of water, the temperature it is exposed to, what impurities are in the water and in what concentration.
The amount of time it would take to freeze a 400Ml bottle of water will depend on the temperature of the freezer. On average this takes about 3 to 5 hours.

pee n ................... you didnt continue but ok ill answer for p as long as water does
At -20 it will take a 5 gallon bucket 10 hrs to freeze solid!
4 hours
If it is placed in a standard freezer (or the freezer compartment of a fridge) it will not completely freeze; most will be solid over night. However, if the setting is low enough, it can take about the same time as water to freeze, which can be anywhere from 4 to 8 hours.
it takes about 1 hour
It... melts...? How do you not know this? This is basic knowledge.
it takes 30 min for it to freeze
This depends on the volume, initial temperature, geometry of the bottle, type of freezer, etc.
