It has been proven that hot water freezes faster than cold water.
The time it takes for hot water to freeze depends on factors such as the initial temperature of the hot water and the surrounding temperature. In general, hot water will freeze faster than cold water due to the Mpemba effect, which is the phenomenon where hot water freezes faster than cold water under certain conditions.
The purpose of conducting the "Does hot water freeze faster than cold water" project is to investigate and understand the phenomenon known as the Mpemba effect, which suggests that hot water can freeze faster than cold water under certain conditions. This project aims to explore this concept and potentially uncover new insights into the freezing process of water.
Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
The Mpemba effect, which causes hot water to freeze faster than cold water when thrown into the air, is due to a combination of factors such as evaporation, convection, and supercooling. The hot water evaporates more quickly, leading to a decrease in volume and temperature, which accelerates the freezing process.
The Mpemba effect, where hot water freezes faster than cold water, is a complex phenomenon that is not fully understood. Some possible explanations include faster evaporation of hot water, differences in dissolved gases, and changes in the structure of water molecules.
cold water
Cold water freezes faster because hot water has to cool down to the freezing temperature before it can freeze.
Cold air and hot water makes water freeze faster simply because the hot water is steaming and so the result is that there is less water to freeze. hot water = steam = less water less water = faster freeze cold air = faster freeze

I believe hot water freezes faster because it is supercooled. Cold water is non-supercooled. When cold water freezes ice crystals form and float to the top, forming a layer of ice over the top of the water, so the layer of ice stops evaporation . While the hot water, which is probably no longer hot in the freezer,when it does freeze, it freezes throughout, creating more or less of a slush before freezing solid.
The fact that hot water may freeze faster than cold is often called the Mpemba effect

No. It takes longer to freeze because cold water is closer to it's freezing point.
cold water is best because it will freeze faster
The materials needed for the experiment are: two containers to hold the water, hot water, cold water, thermometers to measure the temperature, a freezer to freeze the water, and a timer to record the time it takes for each to freeze.
Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
