Basically, the rate at which the water will cool depends on the difference between the water's temperature, and the temperature of its surroundings. The higher the temperature difference, the faster it cools. There are some other factors, but that's the gist of it...
hot water with cool water
In every day life yes, adding cool water to hot water will even out the temperature, making it warm and therefore decreases the time it takes to cool down. But this is not neccesarily the case scientificly as warm water may not decrease at a faster rate than hot water.
I doesn't cool faster. but if you can prove me wrong which you problly can it would be because of the room tepiture of temp. around like in the air. hot water is made its is really cold water a higher tempiture. so when hot water is left out with nothing to control its tempiture. so than that is why hot water cools faster. besides cool water cant cool if its already cold.
The reason hot water cools/freezes faster than cool water is because of the difference in temperature of the water & the room/freezer. The greater the difference, the greater the difference in the rate of heat exchange. In other words, hot water gives off its heat at a much faster rate than cool water does. That is not to say hot water will freeze in less time than cool water, but warm water will.
Hot/warm water will only freeze faster then cool water when the cool water has more minerals in it (hard water). When water is heated it will loose many minerals contained within making the water more pure. If the cool and hot water have the same amount of impurities (minerals) then, the cool water will freeze faster since it needs to exchange less BTU's to freeze.
The answer to this question depends on several factors. First, what is the volume of the water, and what shape is the container? Two gallons of water in the same shaped container as a gallon of water will cool at a slower rate. A gallon of water in a cube will cool more slowly than a gallon of water in a flat tray, because the water will exchange heat with its surroundings at the surfaces, and the water in the tray will have a much higher surface to volume ratio. Also, you really haven't defined hot and cool in your question. Once you do define those aspects, you have to also define what the surrounding temperature of the air or fluid into which the hot or cold water's container is placed. You'd also want to know the altitude, since that will affect the rate of heat exchange as well. So, there really is no answer to this question, except the empirical answer that you can get by just putting a thermometer in the hot water and watching the time it takes to reach your desired cool temperature.
hot water drops faster because themolecules presser it witch makes it go faster
it becomes cool
water because when they make maple syrup it is 95% water and to make the syrup better they boil off the water
It get hotter and if it is frozen it melts. If it is melted it boils.
Both are Super sexy!
the water molecules are getting cold
Yes it would cause it has water in it
the temperature at which it is being cooled
Cool water moves slow because the molecules are moving slow. In hot water, molecules are moving fast, thus, hot water seems to move faster than cold water at times.
I don't think that is possible. How can "hot" make "cool" water "cold"? (also, 'hot ice' is boiling water)
heat transfer from hot water to cool water by touching then the velocity of hot water decrease or its temperature decrease.
The hot water warms the refrigerator, which forces it to turn on to cool it off.
yes, hot water just cools down cold water will turn into ice which will take longer
If you let hot water cool down, it will become cold water.
That depends on what temperature the pure water is at. Pure water in general does cool faster, however.
If the liquid is not very hot, stand it in a container of water. Leave it in a cool place. Direct cool air onto it.
to cool them off or they die fast
the get kinda hot cool them with warm water though k
