1. Water. When being frozen at sea level, between the temperatures of +3.98°c and 0°c, something magical happens... At +3.98°c, water is at it's most dense (natrually), and so freezes into a solid. Between +3.98°c and 0°c, water becomes less dense, hence thawing and appearing "warmer", whilst actually getting colder, until at 0c, it freezes again.
Didn't any of you know this? How do you think your fish survive in winter when your pond freezes over? The top is frozen, as it is around 3.98°c, but the water underneath is between +3.98°c and 0°c.
No, in fact I did not know this.
Interesting theory. Water freezes at 0o C, not in 3.98o C. At near 4o C water becomes dense. As the temperature becomes cooler, density falls and when it comes to 0, ice is formed. This is the Basic law of thermal physics. That is why ice floats over water. fish survives as ice is floating over water and warmer water is beneath ice. NOT like your theory
Thanks for correcting the above, but I think this is missing the basic point. Solid water (ice) is less dense than liquid water (water), regardless of the temperature of the liquid water.
