cold water
yes
Cold.. just enough to freeze water..
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.
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.
no because the cold water speeds up the process by starting it
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.
Yes you can I have it on good authority that you can freeze anything. You can even freeze your posterior off in really cold weather. So be careful!
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.
They live in cold climates and swim in cold water, the fat layer is necessary to keep them warm so they do not freeze to death.
Everything would get cold and, if cold enough, would start to snow and freeze water.
An unresolved question! See Mpemba Effect in wikipedia for the best experimental conditions for this anomaly!
The water balloons will remain intact but will reach the same temperature as the cooler. If the cooler is cold, the water balloons will also be cold. If the cooler is warm, the water balloons will also be warm.
