Why does all the water in a lake have to be cooled to 4 degrees Celsius before water can be cooled below 4 degrees Celsius?
Water in a lake is usually cooled by the cold air above its surface rather than from the ground underneath it. As the top layer of water cools its density increases and so it sinks to the bottom, bringing other water up to the surface. This water is then cooled. This carries on until the temperature reaches 4 deg C when the density reaches a maximum. Further cooling lowers the temperature of the top layer but now its density is less than that of the water below so the top layer stays on top until it freezes (if it is cold enough). That is how you can get lakes with a frozen surface but liquid water below which can sustain aquatic life and also destroy human or other life forms that fall through the ice!
How does water get down your throat?
It goes down your throat and in to your intestines until it reaches your bladder.
What happens to the rain when it reaches the surface?
If enough rain falls, upper layers of the soil will not be able to absorb all the water. When this happens , the water continues downward until it reaches an impermeable material.
A muscle fiber will not respond to a stimulus until that stimulus reaches what?
it will not respond until it reaches the threshold level
What will happen to the water if you put a cup of water in a kettle and place it in the flame?
The water will warm until it reaches the same temperature as the flame. If the flame is hot enough, the water will eventually boil when it reaches 100ºC, and will then be converted to steam (water vapor).
As water is cooled its density does what until it reaches about 4 C?
As water is cooled its density increases until it reaches about 4 C and then it decreases.

Does water contract or expand when it is cooled?
When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%
Where does the water go when it reaches land?
When water reaches land it can flow across the land until it reaches rivers, lakes, streams or the sea.

What happens to gas as it i cooled below 0 degrees C?
It continues to cool until it reaches it's boilng point. At which it will condense then cool further until it reaches it's melting point. It will then continue to cool until it's entropy is minized at absolute zero.
What happen when you heat ice?
First the ice gets warmer, until it reaches its melting point. Then it turns into water. THen the water gets warmer, until it reaches its boiling point. Then the water evaporates as steam.
Where does the water fall water go?
It travels through the river until it reaches the ocean.
Is a Honda goldwing 1100 oil cooled or water cooled?
Water cooled.
What happens to cooling system when engine is cold?
the water continues to cycle through the water pump, radiator, and heater core until the engine reaches sufficient temperature to open the thermostat. when the thermostat opens, cooler water enters the engine block and heads and warmer water is pulled out of the block, enters the radiator to be cooled, and the cycle continues
Is Air cooled vs water cooled pocket bikes?
water cooled is better
