For one, there's this cool effect called the Mpemba effect stating that hot water freezes faster than warm water. But I expect that this is not the answer you're searching for.
Hot water has a faster cooling rate (the loss of heat energy) than cold water as it has a greater difference in temperature to the surroundings. This is Newton's law of cooling
Wikipedia definition of the law is " that the rate of heat loss of a body is directly proportional to the difference in the temperatures between the body and its environment"
