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.
Why is there more pressure at the bottom of the pool than at the top?
More water on TOP of you.
Water freezes at 32 degrees on what temperature scale?
On the Fahrenheit scale. Water freezes at zero on the Celsius scale.
What imperial unit when at 32 freezes water?
Water freezes at 32 degrees Fahrenheit and 0 degrees Centigrade
Is denominator on the top or bottom?
Numerator on top; denominator on the bottom.
How does anomalous expansion of water help aquatic organisms in cold climate?
Aquatic life is benefited by the anomalous expansion of water because the water freezes top to bottom, not bottom to top. If it froze bottom to top, then the aquatic life would be pushed up, up, up, towards the surface of the water. Since it goes top to bottom, and the water at the bottom remains at 277K, the Aquatic life can survive there.
What prevents the lakes of colder parts of the world from freezing solid from bottom up?
Ice is 9% less dense than water so it floats. When water freezes it floats to the top so the water (liquid) is always at the bottom.
Why do pond freezes 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.
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 ice build on a lake?
water freezes from the outside to the inside. when a lake freezes, the top turns to ice first.
If hot water rises how come the top of a pond or cup of water freezes first?
The ground stays warmer. so the top is frozen first because it comes in direct contact with the cold air, and the bottom is in closer contact to the warmer earth.
How can fish live in a frozen lake?
The top freezes. Under the frozen top is liquid water.
What is unique about water in terms of matter?
It is denser than air. So, water freezes from the top down.
Does the bottom of the universe have water?
The universe has no top or bottom.
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..) ... Have a great day....An Engineer
Why does water not become ice at the bottom of the sea?
Water has the highest density at 4 degrees celcius. So when there is ice at the top, the temperature increases to the bottom. Only when all the water is cooled off, it freezes. If water behaved like most other materials, it whould just get heavier as the temperature decreases, and lakes would freeze from the bottom. Without circulation, they might never thaw in the summer.
Does water expand?
When it freezes.
