water cools quicker because it evaporates. It's why you feel cool when the wind hits your wet skin in dry climate.
It takes longer to cool off, but mostly depending on the temperature.
Water takes longer to heat up and to cool down then it does for land.
Bubbles last longer in cool water because the cold water doesn't take energy from the bubbles
yes, hot water just cools down cold water will turn into ice which will take longer
Water takes longer to cool down because it has a high specific heat capacity, meaning it requires a lot of energy to change its temperature. Additionally, water is a good conductor of heat, allowing it to distribute heat throughout its volume efficiently. These properties make water slower to cool down compared to other substances.
Salt, if you put it on ice, melts the ice. So that probably what is causing it not to freeze as fast.
Because the specific heat of water is very high. In fact, water has about 1400 times more heat carrying capacity than air.
The reason it takes longer for a kilogram of water than a kilogram of copper to reach the same temperature is because of the specific heat capacity of each. This is the amount of energy (heat) it takes to raise the temperature of one kilogram of material by 1 degree Kelvin or Celsius.
Copper bathtubs will not corrode or rust. If not properly taken care of, however, they can take on a slightly greenish color. Copper bathtubs are excellent heat absorbers and will keep the bath water hot longer than traditional bathtubs.
No, adding salt to water does not make it cool down faster. In fact, adding salt to water lowers its freezing point, which means it will take longer to freeze but will not cool down faster.
I hand wash my underwear in the sink ... Cool water, no bleach, mild or natural detergent - air dry. They last a LOT longer this way..
If the water's pH is more acidic (lower pH) then the effects of copper corrosion will be faster and more pronounce. If the water is less acidic (Higher pH) copper corrosion will take longer and be less pronounce.
