Well, it does NOT. Because hot water has to cool down first from 45-100oC back to 0oC and cold water only from 15-5oC back to 0oC. This means that 3 to 20 times more energy (heat) has to be transferred to a cooling agent (of less than 0oC).
In practice however a lot of disturbing influences might occur. Even for the socalled Mpemba Effect there is no scientific explanation at all, though the observation has been verified.
A2. But just before you shut your mind, check out Mpemba Effect in Wiki.
And to round out your thermodynamics, try Leidenfrost Effect, where a low pressure boiler evaporates water faster than a high pressure one.
A3? Now! I don't actually understand HOW this happens...But!...It DOES happen! Today is 1-23-11...it was 4 Degrees F this morning. I woke to find the HOT water to my washer frozen BUT! NOT the cold? That is the 2nd time this week that this has happened! Back when I was in high school taking chemistry, me and my dad argued over this question more than once...I KNEW it couldn't be possible! But! now...over 40 years later...I have to admit...I've seen this happen DOZENS of times!?!?! Here's the conditions that this occurred...maybe this will inspire someone to figure it out...I would sure like to know the answer!
CONDITIONS: I have 2 x 1/2" PCVC lines about 35' long ran from the source (Hot & Cold) inside of a gray dense foam tube. All joints are sealed with Duct Tape. Several feet of both ends, source & where it goes up through the floor to the washer are also wrapped with fiberglass insulation and then covered with reflectix (Foil covered bubble wrap). That leaves 20' - 25' that is just in the foam tube. I thought that by running the hot & cold together in one insulated tube instead of insulating them separately would keep it warmer inside the tube to help keep things from freezing! I woke up to 4 Deg. F and Frozen hot but not cold?!?!
What else can I help you with?
How long will it take for warm water to freeze?
The time it takes for warm water to freeze depends on factors such as the initial temperature of the water, the volume of water, and the surrounding temperature. Generally, warm water will freeze faster than cold water due to the Mpemba effect, but it still typically takes a few hours to freeze completely in a standard freezer.
Does warm water evaporate faster than cold water?
Yes, warm water evaporates faster than cold water because the molecules in warm water have more energy, allowing them to escape into the air more quickly.
Does cool water freeze faster than warm water?
Absolutely. Water must achieve a temperature below 32°F before it can freeze. The closer the water is to room temperature, the quicker it will freeze. There is a phenomenon in which warm water freezes and cold water not: In some regions(e.g. Siberia) it is possoble to pour boiling hot water to the ground and it will freeze even before it hits the bottom. This is possible as hot water's molecules are moving more heavily than those of cold water. Therefore the surface of the water is bigger and warmth can leave the molecules faster. I remember a report of a experiment at one of the university's found hot water froze faster by a inute.
Data of does warm water freeze faster than cold water?
AnswerHot water doesn't freeze fasterAccording to www.sciensational.com, hot water freezes faster than cold water.But I do not have any idea about your question.lllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll
Does sound travel faster through cold water or warm water?
Sound travels faster through warmer water because warm water molecules are more spread out, allowing sound waves to travel more quickly. Cold water, with its denser and more closely packed molecules, slows down the transmission of sound waves.
Do cold water freeze faster than warm water?
yes
Does warm water freeze faster than cooler water?
no because the cold water speeds up the process by starting it
What freezes faster warm water or cold water?
Cold water, less energy must be removed from cold water to make it freeze. warm water has more energy which needs to be removed before it freezes. it is an urban myth that warm water freezes faster.
What will celery absorb faster warm or cold water?
Celery will absorb water faster in warm water because the molecules of warm water are more energetic and can penetrate the celery cells more quickly. This allows for quicker absorption of water by the celery.
Does warm or cold water freeze first?
cold water
How long will it take for warm water to freeze?
The time it takes for warm water to freeze depends on factors such as the initial temperature of the water, the volume of water, and the surrounding temperature. Generally, warm water will freeze faster than cold water due to the Mpemba effect, but it still typically takes a few hours to freeze completely in a standard freezer.
Do flowers drink cold water or warm water faster?
cold water faster
Does a boat sink in hot warm or cold water faster?
It sinks faster in hot water than warm or cold
Why does water freeze faster?
because water is generally cold unless heated in a kettle. Coffee on the other hand is warm when you make it so if the water is colder to start with it will take less time to freeze.
Does warm water freeze faster than cold water?
An unresolved question! See Mpemba Effect in wikipedia for the best experimental conditions for this anomaly!
Which moves faster cold or warm water?
Warm water of course.
Which freezes faster cold warm or hot water?
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.
