well whoever asked this is an idiot. obviously it's gonna get cool. wow.
the heat from the hot water will be lost to its surrounding.
The flow and return on a calorifier are used to circulate hot water from a heat source into the calorifier and to return cooled water back to the heat source for reheating. This helps maintain a consistent supply of hot water and ensures efficient heating of water within the calorifier.
If a hot saturated solution is cooled quickly, the solubility of the solute decreases with temperature, causing excess solute to precipitate out of solution. This rapid cooling can result in the formation of larger crystals or a higher amount of crystals in the solution.
when water vapour is cooled it condenses and falls as rain
Hot water can freeze faster than cold water due to a phenomenon called the Mpemba effect. This effect occurs because hot water can evaporate more quickly, losing some of its volume and cooling faster. Additionally, hot water may have fewer dissolved gases, which can also aid in faster freezing.
it depends on which cool. Like the cool as in hot and cold it would be cooled. But, if it was for popular it would be ,was cool
Only hot air rises, so if the hot air was cooled..... it would fall. Splat.
Crystallisation
It must be cooled to 0 oC.
it goes threw a cycle
Yes, but it must be cooled to 0 oC.
the temperature at which it is being cooled
Under O oC water become ice (a solid).
Expands
It is hot and must be cooled before consumption.
Seeds can germinate in cooled boiled water, so long as the water is no longer warm or hot. The act of boiling will actually clean the water, causing it to be sterile.
Covered by a protective toweling, the hot-water bottle is placed on the treatment area and left until the water has cooled off.
Most hot springs are heated from below and cooled by the air above. This tends to make the top of a spring cooler than the bottom. As a result the air-cooled water winks while the newly warmed water rises.
