well, pretty cold, i quess. i would think 32. Just like reqular water. if you leave the hot water outside it will eventually cool and freeze
When I grew up in Fairbanks, Alaska, we would go outside when it was below -60 degrees Fahrenheit, and toss a glass of hot water into the air. If cold enough, the water droplets would crystallize in the air before hitting the snow. If not quite cold enough, water would hit the ground, and freeze in seconds.
The process of water freezing into ice involves the temperature of water being lowered to 32 degrees Celsius. Hot water will take longer to freeze because the difference between the temperature of hot water and 32 degrees is greater than the temperature of cold water and 32 degrees.
When a hot can is placed in cold water, the air inside the can cools down and contracts, creating a lower pressure inside the can. The higher pressure outside the can then crushes it.
Hot water with salt will freeze faster than cold water because the salt lowers the freezing point of water. This means that the hot water with salt will need to cool to a lower temperature before it can freeze, making the freezing process faster compared to cold water.
Salt dissolves faster and more easily in hot water compared to cold water because the increased temperature in hot water provides energy that helps break down the bonds holding the salt molecules together. In cold water, there is less energy available to overcome these bonds, resulting in a slower dissolution process.
cold water
Cold water freezes faster because hot water has to cool down to the freezing temperature before it can freeze.
cold
hot
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 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
Kinetic energy
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.
it changes the temp. by the temperature outside,like if its cold out the water will be cold and if it's hot outside than the water will be hot
it Dosen't
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.
Cold water lines may have more insulation than hot water lines, otherwise they should both freeze unless there is some agent in the water.
