I put all the water in the freezer at 9:00am.
At 10:00 I checked the water,the warm water was not frozen, neither was the cold water or the freezing water and especially the hot water.At 11:00 I checked them and the only one that wasn't frozen was the hot one.
Cold tap water
The cold froze at 10:30 it took 1hour and 20 minutes to freeze.
Warm
It froze at 10:30 and took 1hour and 30 minutes to freeze.
Cold
It froze at 10:30 and took 1 hour and 30mins to freeze.
Hot
It froze at 10:47 and took 1hour and 47 minutes to freeze.
Conclusion:The hot water took 17 minutes longer to freeze because it had to cool down first.
