A teperature under 0 oC.
Freezing
The water in the ice tray had not hardened into ice cubes as the refridgerator's temperature had not yet reached the freezing point of water.
Yes, by putting sprite in an ice cube tray and freezing themm..
Ice cubes you use to cool your drinks after you put the water in the freezer, Ice burgs....
If Ice cubes are melting in water, the temperature of both the ice cubes and the water will be exactly the freezing temperature of water: 32F, 0C. You cannot change this. You can add heat to make the ice cubes melt faster, but the extra heat will have no effect on the temperature, It will all go to melting the ice cubes.
well when water changes into ice its a form of physical change
This will depend on the source of your water. In most developed countries, it is not necessary to boil water before freezing it for ice cubes because the water is safe to drink. However, in developing countries that don't have consistent safe pathogen-free water, you should boil the water to kill any of the bacteria in it before freezing it into ice cubes.

because ice is made by freezing water but hot water is the opposite that is why it melts fast
hot water takes longer @$$
Its a physical change because it can be reversed by re-freezing the water.
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
