Good question. While hot water does not freeze quicker than cold water in all cases, it's true more often than not from what I have heard,
it's basically a theory that as the difference between starting temp and finishing temp increases, the rate of cooling observed in the water will also increase correspondingly.
this is because when boiled, the water absorbs thermal energy (heat) and as we see in nature, when energy is placed in an environment with significantly less of that energy form, the cold air is "thermophilic" meaning the energy in the hot water is attracted out of the hot water, into the cold atmosphere, until equilibrium is met (or in the case of a freezer that is adjustable through a thermostat, the water wouldn't stop cooling until it reaches the temperature on the thermostat)
The fundamentals of what happens is similar to how coil magnets work when varied levels of electric energy are applied. A heavier electric current causes a stronger magnetic pull in a similar way that a greater difference between freezing and boiling causes a stronger thermal energy transfer from the water into its surrounding atmosphere. Just like with magnets, if the magnets are too weak, or if the water you are freezing does not have a large difference in temperature from what temp it is starting at, it is possible that there may not be enough energy here to even trigger a reaction at all. Like when magnets are a certain distance away, they don't pull one another anymore.... when the difference in temperature between the liquid and the air around it goes below a certain point, think room temperature, you see nothing more than a very slow trickle of that thermal energy out of the water, if you see the water cool at all. The water at cooler temperatures has been "charged" with less thermal energy and also not heated warm enough to produce steam, thus cannot initialize a rapid, stemy transfer of heat that you would see with hotter water.
one little experiment you could do at home if you choose to try this one for yourself and want a further understanding of how heat equilibrium works, compare the difference in time it takes between a) make boiling water freeze vs b) make boiling water reach room temperature, also measuring room temperature before boiling water is added and room temperature after temp has equilibrated, and c) try experiment b in the refrigerator, checking to see how much warmer the fridge gets when you put something hot in it, also noting how long it takes for the water to stop yielding heat to its surroundings.
What else can I help you with?
Would a jug of hot water or half a jug of hot water go cold quickist?
Half a jug as the surface area to volume ratio is reduced therefore heat can escape quicker from the surface
Why will coffee powder dissolve quicker in warm water than In cold?
Coffee powder dissolves quicker in warm water than in cold water because the molecules in warm water have higher kinetic energy, which allows them to move faster and collide more frequently with the coffee particles. This increased collision rate leads to a faster dissolution process. In cold water, the lower kinetic energy of the molecules slows down the dissolution process.
Does warm water feeze quicker than cold water?
Under certain conditions, warm water can freeze faster than cold water, a phenomenon known as the Mpemba effect. This is believed to occur due to complex interactions between factors such as evaporation, dissolved gases, and supercooling. However, the exact reasons for this effect are still debated among scientists.
Which boils quicker warm or cold water?
Warm water will generally boil faster than cold water because warm water is already starting with a higher temperature, so it requires less energy to reach the boiling point.
Dose hot boil faster than cold water?
Yes, hot water boils faster than cold water because the molecules in hot water have more energy and are already closer to the boiling point. This means it takes less time and energy to raise the temperature of hot water to the boiling point compared to cold water.
Does hot water melt ice quicker than cold water?
it does melt it quicker i checked
Is it better to use a fridge or cold water to cool something?
Running cold water is the quickest way to cool something, especially Baby Formula. Agitating the bottle under a running cold tap, will cool it to the required temperature quicker than anything else, including putting it in the freezer.
Would a wet animal cool quicker than a dry animal?
An animal that is wet will dry quicker because when your wet your cold when you get out of the shower.
Why water evaporates quicker on a hot day than a cold day?
Hot water need less energy to be evaporated than cold water.
Why does bath water take longer to cool than tea?
When you make a cup of tea, you boil the water to between 90 and 100 degrees centigrade. The molecules in the liquid water are at a higher energy state and get to lose their energy quicker. The water in a bath is usually at 50 to 60 degrees and at a lower energy state therefore will lose its heat more slowly. The same effect is noticed if you use hot water to melt ice on a path rather than cold water. The hot water loses its energy quicker and would turn to ice quicker than the cold water.
Why do raisins plump up more quickly in hot water than in cold water?
Raisins plump up more quickly in hot water because the molecules in hot water move quicker than molecules in cold water so the hot water molecules diffuse quicker into the raisin.
Why salt dissolve faster in hot water than in cold water?
salt dissolve quicker in hot water because it practicaly melts the salt there fore making it quicker to dissolve.
Will large particles cool water quicker than small particles?
If you have a handful of cold particles, and you want to toss them into a glassof water in order to cool it, then it'll happen faster if the particles are small.That way, there is more cold surface area in contact with the water toconduct heat out of it, and all of this is the main reason why the bartenderuses crushed ice in most drinks.
Why cold water thaw frozen foods faster than in air?
Cold water has a higher thermal conductivity than air, meaning it can transfer heat more efficiently. When submerged in cold water, the water extracts heat from the frozen food at a faster rate compared to in air, leading to quicker thawing.
Does water take longer than copper to cool?
water cools quicker because it evaporates. It's why you feel cool when the wind hits your wet skin in dry climate.
Does hot water get colder faster than cold water?
Yes ,the higher the temperature gradient between the hot water and room temperature, the faster it cools. However, that does not mean that hot water will freeze faster than cold water (a common urban legend). If you have water at 50°C in a room at 20°C, it will cool from 50° to 40° faster than it will cool from 40° to 30°.
Why water evaporates on a hot day quicker than a cold day?
The rate of evaporation depends on the temperature.
