Answer 1

if it will be in a duffel bag for 10 hours then you can freeze it until it is frozen. probably take an hour or two. it will definitely thaw in 10 hours.  

Answer 2

The amount of time depends upon the temperature of the bottle and water at the time you put it in the freezer, and how much water there is in the bottle. If you want to be sure that you don't freeze the water, then put in the refrigerator instead of the freezer. After 10 hours in a duffel bag, it should still be several degrees cooler than room temperature.

Answer 3

4 to 5 hours

Answer 4

over night then just rap you towel around it to keep it cold if you want to
