yes, if there is less water there is less to cool down
In the beginning of what ? At the end of what ?Do you mean "Why does hot water cool faster than cool water ?" ?Because the rate at which heat passes from a warm object to a cool objectdepends on the difference in their temperatures. So, as the warm objectbecomes less warm and the difference in their temperatures becomes smaller,the rate at which heat flows between them also becomes less.
Sand cools down faster after dark
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°.
It should be pretty obvious that it will cool faster if kept in an environment which is colder for a longer period.
Evaporation.

sand cools of faster because the sand is less dense and it depends on witch sand beach sand will cool of faster because it is mostly water under it so it will cool of faster
No It's warm water the ? was what cools faster cool water is already cool so warm water will cool faster. Plus cool water gets warm Also back in the sixties a experiment was done Hot water froze faster than cold water by a minute . ( I remember this from the Weekly Reader report. lol lol ) I also believe it's meant to suggest when the water is at room temptureroom temperature.
who cares about water
That depends on what temperature the pure water is at. Pure water in general does cool faster, however.
beacause its solid
Mpemba effect ,water evaporates faster so it has less water so it freezes faster
Sand cools down faster after dark
NO
You would cool a bucket by putting ice into the water.
yes because you have to know which one grows faster with warm of cooler water..!
Yes, usually.
