what will be the minimum temperature at the bottom of the pond?

Question

if answers to the question is 4 degree c ,then what is the reason

Answer 1

Surprisingly, it can go to -(infinity) degree celsius and yet still remains in liquid form, depending on the depth and pollution of the pond. This is due to the pressure acting on the water below. Higher pressure means lower temperature to get frozen. Imagine a extremely deep ocean a over 50 60 kilometres down.. the pressure will be so big!! anyway at this depth u will be reaching the lava and the water will be way over 100 degree celcius! the water pressure is way too high for the water to boil into steam... Well.. the answer i gave is what i know from the TV... im not very sure of the actual answer though

Answer 2

Other responders are mostly correct: 4 C is the number. Water is most dense at that temperature, so water either colder or warmer than that will be displaced upward by it.

I found previous responder's answer confusing. Water can be supercooled: it may be chilled to colder than 0 C and not freeze unless agitated or an ice crystal dropped into it. (You can demonstrate this with your refrigerator.) At high pressures, water, like other liquids, is retarded from evaporating. Suppose you have a very strong bottle, half full of water and half full of wate vapor. The bottle is equipped with temperature and pressure gauges. As you raise the temperature, the pressure increases; the liquid becomes less dense (it expands a bit) and the vapor becomes more dense (compressed by its own pressure). You can draw a graph showing the relation between temperature and vapor pressure. As the pressure and vapor density continue to increase, there will come a point where the vapor density is the same as the liquid, and there is no longer a distinguishable boundary between the two phases. This is called the critical point; for water, it is at 374 C. and 3216 PSI, and it is at this point that the graph ends.

Answer 3

Yep 4 degrees C is correct.

Water is the strangest substance in the universe. It expands when it gets from liquid to solid. Water is at it's densest at 4 degrees. The reason for this as the water molecules begin to form the hexagonal crystals. It is also why the temperature under a plane of ice is 4 degrees C. (Except in salt water)

Answer 4

What depth is the pond?

Answer 5

it will b 4* .. this is Due to the anomalus behaviour of water

Answer 6

umm I need more data.
