The most natural coldest thing on the earth is the ice of Antarctica.
What is the coldest substance known to man?
Liquid hydrogen is the coldest substance known to man, minus 400 degrees. ALSO: A Bose–Einstein condensate (BEC) is a state of matter of bosons confined in an external potential and cooled to temperatures very near to absolute zero (0 K, ?

Is dry ice the coldest thing on earth?
Atop a ridge in Antarctica, temperatures can drop below -136 degrees F. (Inside Science) — According to new measures, the lowest natural temperature on Earth is colder than -136 F. The temperatures can be colder than dry ice. …
What is world’s coldest substance?
Scientists just created the coldest substance on Earth, and it has some really weird properties. Researchers chilled sodium potassium to just 500 nanokelvin. MIT/Jose-Luis Olivares Physicists have chilled molecules to just a smidgen above absolute zero — colder than the afterglow of the Big Bang.
What is the most coldest thing in the world?
The protoplanetary Boomerang Nebula, located 5,000 light-years from Earth, holds the record for coldest known object in the Universe. Outflows of gas, streaming out from the central dying star, reach temperatures below -270 degrees Celsius.
What is the hottest thing in the universe?
The hottest object in the Universe, literally speaking, is the Big Bang. If we go back in time, the Universe gets denser and hotter without a limit. The Big Bang singularity marks the breakdown of Einstein’s theory of gravity, where the density and temperature of matter and radiation diverge to infinite values.
What’s the hottest substance on earth?
By zapping a piece of aluminum with the world’s most powerful x-ray laser, physicists have heated matter to 3.6 million degrees Fahrenheit (2 million degrees Celsius)—making it briefly the hottest thing on Earth. Only locations such as the heart of the sun or the center of a nuclear explosion are hotter.
What’s the coldest water you can drink?
The answer definitely isn’t 32 degrees Fahrenheit, even if that’s the freezing point of water. If the conditions are right, water can remain liquid all the way down to minus 55 degrees.
IS 16 C hot or cold?
For someone from a cold country 16°C (60°F) is a lovely, almost warm, spring day. You might find it a bit chilly but it’s not really cold, you should be OK with long pants (or tights if you’re wearing a dress or skirt), a sweater and a light jacket.
Is C the same as F?
Celsius and Fahrenheit are two important temperature scales. … The two scales have different zero points and the Celsius degree is bigger than the Fahrenheit. However, there is one point on the Fahrenheit and Celsius scales where the temperatures in degrees are equal. This is -40 °C and -40 °F.

Is it bad to eat dry ice?
Never eat or swallow dry ice. Avoid inhaling carbon dioxide gas.
What happens if you touch dry ice?
The Effect of Dry Ice
Like a very hot object, like a stovetop, dry ice has the same effect on skin and can cause a burn. If you touch dry ice momentarily without protective gear, it can cause redness to the affected skin. If you hold dry ice in your hand for a longer time, you can get frostbite.
Is dry ice toxic?
DRY ICE EXPERIMENTS Dry Ice is not poisonous, but it is extremely cold and can cause cryogenic burns to unprotected skin. Please take precautions when handling dry ice; thick leather gloves should be worn when handling to avoid cryogenic burns. Children should always be supervised when dry ice is being used.
