hot water
a combination of evaporation and a higher degree of hot/cold segregation leads to this

Hot water because when I talk to hot women they give me the cold shoulder whereas cold women warm up to me

If you put hot water in the freezer, the freezer thermostat will turn on, causing the water to freeze faster than if it were cold.

Cold water.

Less energy is required to cool it to freezing.

It sounds weird but try it: put a glass of warm water and a glass of cold water in your freezer at the same time.

the word "water" refers to H2O in its liquid form
we call water that's already been frozen "ice"

Mpemba effect is real but gets memed. It does happen sometimes but it's unpredictable and unreliable because the mechanism for its action has not been determined. There's no answer to the question as it is given because both outcomes are possible under different unspecified conditions.

Cold water. I define hot water as water which is 99C and cold water as 1C. Mpemba effect has no influence on the outcome.

This, dont post stupid questions with not enough background evidence OP. That's like going "what will live longer, a mite or a tortoise?" And the answer is "Ackshully the mite is the longest living mite and the tortoise died minute after being born.

hot water because heat transfer is statistical and it's statistically more likely to transfer heat if the water molecules have more energy

How could you ask this question without specifying the precise temp ? You aware 10000K water is still water ?? DONT YOU ???

Hotter than 100C and it's steam at atmospheric pressure, which is the default if none is specified. Don't be an autist. Your point was addressed without being hyperbolic in >>12026076

Until they have transferred enough that they are the same temperature the cold water started at; during which time the cold water was getting colder.
