Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.
Using thermal mapping, scientists tracked the volcano's emissions with temperatures upward of 1,179 degrees Fahrenheit. Lava is the hottest natural thing on Earth.
Answer and Explanation: Magma is hotter than lava, depending on how recently the lava reached the surface and if the magma and lava are from the same magma chamber below the volcano.
The temperature of magma is slightly hotter and ranges from 1300 to 2400 degrees Fahrenheit. The temperature of lava is slightly colder and ranges between 1300-2200 degrees Fahrenheit.
Close to Earth's core, the mantle's temperature can be as high as 4000 °C. But near the surface, the molten rock (or magma) is a lot cooler. In fact, as it spills out onto Earth's surface as lava, the runny rock's temperature is only a little lower than the hottest part of a candle flame: about 1200 °C.
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. What is this?
Blue flames usually appear at a temperature between 2,600º F and 3,000º F. Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames.
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.
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.
Ultramafic lava
Ultramafic lavas, such as komatiite and highly magnesian magmas that form boninite, take the composition and temperatures of eruptions to the extreme. All have a silica content under 45%. Komatiites contain over 18% magnesium oxide and are thought to have erupted at temperatures of 1,600 °C (2,910 °F).
Now, falling into lava is another story. The extreme heat would probably burn your lungs and cause your organs to fail. “The water in the body would probably boil to steam, all while the lava is melting the body from the outside in,” Damby says.
Lava won't kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn't get out, you wouldn't die.
More commonly, lava enters the sea via near-surface tubes encased within the bench, building at the ocean edge. The basalt forms elongate lava tongues and channelized flows that extend up to 70 m (230 ft) down the steep submarine slope. The temperature of the lava in the tubes is about 1250 degrees C (2,200 degrees F).
The basaltic lava shooting out of the Cumbre Vieja volcano on the Atlantic island of La Palma, for example, is around 1000°C. But black lava, fresh out of the pit, erupts at 500°C, only 400 degrees hotter than the water boiling in your kettle.
Actual lava is red-orange in color, given its temperature. Truly-blue lava would require temperatures of at least 6,000 °C (10,830 °F), which is much higher than any lava can naturally achieve on the surface of the Earth.
The colour of lavas can be associated with the temperature reached at the surface: dark red at low temperatures (475°C), orange at 900°C and white at extremely high temperature (>1150°C) (Kilburn, 2000).
So lightning essentially is just when charges get separated and come back together. And in doing so they end up heating the air where these charges get put back together to pretty extreme temperatures. Up to 50,000 degrees Fahrenheit, maybe even more.
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.
The cooler the star, the more orange to red it will be. So, all lightning is not created equal, as this photo illustrates. A bolt of lightning can travel at a speed of 45 km/s or 160,000 km/h (100,000 mph). It can reach temperatures approaching 30,000 K (55,000 °F).
The physics rule that energy must be conserved doesn't allow any more energy than that which existed at the universe's beginning. The highest temperature that scientists have created — and thus measured — is 2 trillion kelvins.
The Coldest Place on Earth
Researchers studying subatomic particles created a device — called a cryostat — that can create really cold temperatures: An 880-pound (400-kilogram) copper cube reached 6 millikelvins, just six-thousandths of a degree above absolute zero (0 degrees Kelvin) back in 2014.
The continual nuclear fusion, causes energy to build up and the sun's core reaches temperatures of about 27 million degrees F (15 million degrees C).
This is black fire. When you mix a sodium street light or low-pressure sodium lamp with a flame, you'll see a dark flame thanks to the sodium and some excited electrons. “It's strange to think of a flame as dark because as we know flames give out light, but the sodium is absorbing the light from the lamp.
Purple flames come from metal salts, such as potassium and rubidium. It's easy to make purple fire using common household ingredients. Purple is unusual because it's not a color of the spectrum. Purple and magenta result from a mixture of blue light and red light.
Blue flames are the hottest, followed by white. After that, yellow, orange and red are the common colours you'll see in most fires. It's interesting to note that, despite the common use of blue as a cold colour, and red as a hot colour – as they are on taps, for instance – it's the opposite for fire.
