9 cool facts about ice on the Earth! 10/8/2015 • Carry Baker
Today scientists know 16 crystalline forms of ice. The last one discovered in 2009 exists under the pressure of 10,000 atm and at the temperature of -238 ⁰F (-150 ⁰C).
330 kilojoules are needed to melt down a kilogram of ice. The same amount of energy is necessary to warm up this water till 176 ⁰F (+80 ⁰C). Thanks to the high fusing temperature of ice the process of its melting and accumulation softens the Earth's climate.
1,000 kilowatts – this is an average power consumption of refrigeration equipment (or a chiller) used for making and maintaining ice at a typical ice skating arena. The warmth taken from the ice is usually used for space heating.
3,000 atm – such pressure can be created by water if it is prevented from expanding while freezing. This pressure is the reason for cracks that may appear on the roads or in different constructions.
139 ft per day (42.5 m) is the flow velocity of Jakobshavn Glacier, the fastest ice river on the Earth located in Greenland. The glacier carries out to the sea about 70 km3 of ice annually.
916.7 kg/m3 is the density of ice which is almost 8.3% less than the density of water at the same temperature. Due to this fact seas and rivers are only covered with ice and do not freeze through till the bottom.
2,900 000 km3 –this is the amount of ice in Greenland. It is almost 10% of the whole earthly cryosphere which size is about 28 million km3. By the way, there is much more ice on our planet than fresh water contained in all lakes, rivers and shallow underground reservoirs. The largest amount of ice (~ 90% or 25 million km3) is contained in Antarctica.
In 2012, Greenland lost about 375 km3 of its ice while Antarctica lost about 125 km3.
It will take approximately 2,900,000/375 = 7733 years for Greenland ice to disappear completely if the Earth’s climate remains the same as now. Antarctic glaciers are melting slower and may disappear in 200,000 years.
The HST is a huge achievement of mankind. It allows us to learn more about outer space and the furthest galaxies. However, do you know something about the telescope that helped to disclose so many secrets about cosmos?
You won't believe these ridiculous things are helpful but we bet they really work. See yourself!
The greatest genius of his epoch, Albert Einstein is still famous as one of the most talented scientists of all time. He had a remarkable life, full of amazing events and things besides his famous theory of relativity. Today we want to share the most interesting facts about the most recognizable theoretical physicist in history with you.
Beauty of Science project has published a video showing how chocolate dragees M&M'S are dissolved in water in slow motion. The camera with macro effect and 4K resolution gives the impression that a real supernova explodes. It drew attention of publishing company PetaPixel. This is so fantastic!
Technologies keep surprising us! Researchers from Caltech and the University of Illinois at Urbana-Champaign created an amazing example of biomimicry. A Bat bot is a robot that has silicone wings. Changing shape of the wings during flight the robot looks so natural you wouldn't believe it's a bot! Watch this exciting video and see for yourself.
