For comparison, the
Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There's a catch, though: absolute zero is impossible to reach.
The coldest materials in the world aren't in Antarctica or at the top of Mount Everest. They're in physics labs: clouds of gases held just fractions of a degree above absolute zero.
Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius.
Liquid nitrogen is much colder than ice. Nitrogen is a chemical element in group 16 of the periodic table. This is a group that contains metals, nonmetals, and metalloids. Nitrogen is a nonmetal.
Far outside our solar system and out past the distant reaches of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin). Are you shivering yet?
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).
Physicists acknowledge they can never reach the coldest conceivable temperature, known as absolute zero and long ago calculated to be minus 459.67°F.
At the physically impossible-to-reach temperature of zero kelvin, or minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius), atoms would stop moving. As such, nothing can be colder than absolute zero on the Kelvin scale.
According to AccuWeather, “Only at absolute zero (equivalent to –273.15°C or –459.67°F) would snow become impossible.”
Absolute zero is the lowest temperature possible. At a temperature of absolute zero there is no motion and no heat. Absolute zero occurs at a temperature of 0 degrees Kelvin, or -273.15 degrees Celsius, or at -460 degrees Fahrenheit.
Is lava hotter than the Sun? While lava is still intensely hot, it is not hotter than the Sun. On average, lava can range between 1,300 to 2,200 degrees Fahrenheit, depending on its location. It's safe to say the sun at all parts is much hotter than lava.
Lightning is hot. Really hot. It can reach temperatures as high as 50,000 degrees Fahrenheit, five times hotter than the surface of the sun, and even hotter than lava here on Earth.
Up to 50,000 degrees Fahrenheit, maybe even more.
For intents and purposes, the temperature in space is cold. Very cold. The coolest, or freakiest part, about space, is that there are areas where there are no gas particles, no movement at all, and that is where you'll find the temperature to be at 0 K or absolute zero.
Other astronauts have described it in similar yet varying ways: "burning metal," "a distinct odor of ozone, an acrid smell," "walnuts and brake pads," "gunpowder" and even "burnt almond cookie." Much like all wine connoisseurs smell something a bit different in the bottle, astronaut reports differ slightly in their " ...
Acute exposure to the vacuum of space: No, you won't freeze (or explode) One common misconception is that outer space is cold, but in truth, space itself has no temperature.
The hottest thing in the Universe (Supernova)
Supernovas are the hottest thing in the Universe as they reach a million degrees Celsius. These explosive events occur when a star between 8 and 40 times more massive than our Sun reaches the end of its stellar lifecycle and explodes when its core collapses.
The color of the bolt depends on how hot it is; the hotter the lightning, the closer the color will be to the end of the spectrum. The color spectrum in this case start with infared which is red and the coolest up to ultraviolet which appears violet and is the hottest.
What color is Lightning? Bolts of lightning can come in a variety of colors. Most often we see white bolts of lightning but it can take on any of the colors in the rainbow ranging from red (in the infrared band) to violet (in the UV region).
Lava isn't quite hot enough to melt a diamond, but could a diamond burn in lava instead? In short, diamonds can burn in lava as the burning temperature of a diamond is about 900 °C and lava can get as hot as 1200 °C. The burning process will also, however, require oxygen.
Different parts of our body have different temperatures, with the rectum being the warmest (37℃), followed by the ears, urine and the mouth. The armpit (35.9℃) is the coldest part of our body that is usually measured.
Taking the Moon's Temperature
Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon's poles are even colder.
When all of the molecules (or atoms) in a system stop moving completely, that's as cold as they can get. This temperature, where there's no thermal energy at all, is called absolute zero.
The kelvin, symbol K, is the SI unit of thermodynamic temperature; its magnitude is set by fixing the numerical value of the Boltzmann constant to be equal to exactly 1.380649 × 10-23...
