If heat rises the coldest part of water is the bottom how come it freezes top first i dont know email metalgearclanhotmail.co.uk?
The top of the water will freeze first because it is in direct contact with the air, the bottom will always remain ice free because it is thermally protected against the cold under the ice sheet, (so the fish tell me...) this is why fish will lie at the bottom in cold snaps... if the air temperature is cold enough for a considerable length of time it will eventually freeze completely.
How do you reflect a Axis?
Turn it over so that instead of the numbers going up from left to right (or bottom to top), they go up from right to left (or top to bottom).
Why is there more pressure at the bottom of the pool than at the top?
More water on TOP of you.
Is denominator on the top or bottom?
Numerator on top; denominator on the bottom.
What is the rule in comparing a set of fractions?
the top adds what the bottom adds. the top subtracts what the bottom subtracts. the top divides what the bottom divides. the top multiplies what the bottom multiplies.
Why do ponds freeze from top to bottom instead of bottom up?
Ice is less dense than water so it floats on water. This is useful because it insulates the remainder of the water but also means that aquatic life will not die as they would if water froze upwards.
Is there a well water filtration casing that comes off at the top instead of the bottom?
No, there is not.
When is expanding ice helpful?
When frozen water expands, it gets lighter. So ice can float on top of water instead of sinking to the bottom.
Is a pond cold?
Fish generally go down to the bottom of the pond where the water does not freeze and sort of hibernate for the winter. That is why it is important to make your pond so deep that the water will not freeze all the way to the bottom. (www.rosepond.com)
What planets rotates top to bottom instead of side to side?
Uranus rotates from top to bottom. Stay in school and learn.
Does the bottom of the universe have water?
The universe has no top or bottom.
Why do ponds often freeze in winter but the sea rarely freezes?
When it snows the ice only freezes the top leaving the bottom still water and when you crack that ice the water is still there and the fishes in the sea are still alive. :) i hoped you have learnt

How does the valve functions in bubble top water dispenser?
Bubble top has a replaceable top can of higher capacity and a permanent can at the bottom of lower capacity. When we invert the sealed replaceable can filled with water and place it on the permanent can, the piercing agent in the bottom half opens the seal and water from the top can flows out to fill the permanent can, from which we consume water. While doing so water enters into the top can as bubbles and fills the sapce above the water in the inverted can. The atmospheric pressure outide balances the water in the top can. As we consume the water in the bottom can, water level in the bottom can drops down and exposes the water in the top can. This drops down again to fill the bottom can till the pressure balances the weight of water. (Note ::: if there is leak in the joint between the bottom and top can (Or) If the bottom of the Top can has a minor crack..full water drops from it into bottom and hence spills out..) ...

What would be the effect if ice were denser than water?
Since the density of ice is less than the density of water, bodies of water freeze from the top to the bottom. This actually provides insulation to the water under the ice, preventing all the water from freezing. This allows life to continue under the ice, provided there is sufficient nutrients. If the density of ice was greater than the density of water, bodies of water would freeze from the bottom to the top, providing no insulation, and allowing all the water to freeze. This environment is not suitable for many life forms.
Why do rivers and lakes not freeze easily?
While water is moving, its temperatue can drop below zero and it doesn't freeze. Obviously, faster moving rivers are less likely to freeze. For lakes, water's unique density behaviour protects them from freezing. Unlike almost all substances, the solid form of water (ice) is less dense than the liquid form. Ice cubes float. (For almost all other substances, the "cubes" would sink.) So when lakes freeze, the ice stays at the top. This insulates the remaining water from the colder air above. If ice cubes sank, then lakes could freeze all the way to the bottom: the ice that formed would fall to the bottom, continually exposing the top water to the cold air.
