when filling an ice tray its seems like it takes less time to freeze if the water is warm... is it true?

This true, the higher the heat content the easier the heat is extracted and when the process begins it does not slow when the freezing point is approached.

No in the outdoors, because the water has first to cold to 32 F and then start to freeze. If the water is already cold, it would take less time to start to freeze. The time for the cooling and freezing depend on different factors, as the wind, the air temperature, the sun, the water flows pattern etc.

In the freezer, the cooling rate depend basically on the set-point of the thermostat and the power of the compressor, so it is possible that the freezer start to run for more time if you put warm water inside.

It shouldn't. Cold water has a smaller difference in temperature between its temp when you put it into the freezer, and its temp when it freezes.

But if the water is warm when it is put into the freezer, it may cause the thermostat in the freezer to think the freezer is too warm. This would cause the freezer to run to run, cooling the water more quickly and perhaps making your ice sooner.

The cold water freezes using less energy, but the warm water makes the freezer run, freezing the water sooner and running up your utility bill.

no, think about it. To freeze, water has to reach 32 degrees. If the water is warmer, it takes longer to bring the temp down than if it was already colder. It's just a myth about the warmer water.

It should be false. Ice, as we colloquially call frozen water, is at zero degrees Celsius. Liquid water should be somewhere between zero and a hundred degrees. If you put liquid water in a freezer, the temperature should go lower and lower until it reaches zero. Obviously, if you start at a high temperature, it will take longer to reach zero.

Because of the molecular activity of warmer water it does freeze faster.

no it is not true.
In order to freeze something you need to drop the temp. to it's freezing point, the further the original temp. is from that freezing point, the longer it takes.
