No, the Sun is not the hottest star; there are many stars much hotter than the Sun! You can tell the approximate temperature of a star by looking at its color. The coolest stars are red, then orange, then yellow (like our Sun). The surface temperature of our sun is 5777 Kelvins (~5000 degrees C or ~ 9940 degrees F).১৯ ফেব, ২০১৩

The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

On a stellar scale, it’s really quite average — about half of the known stars are larger; half are smaller. The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.২৬ জুলাই, ২০১৮

While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava. Red lava is colder than candle flames.

Short answer: Yes, there is. Long answer: Blow torches, furnaces, Chlorine Trifluoride burning, Radioactive fire, Surface of stars, cores of planets, cores of stars, supernovas, surface of a neutron star, the whole universe (During first 380,000 years after the big bang) and, finally, a kugelblitz.

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.

Lava, or magma that is on the surface of the earth, is around 1,125 degrees. If you tried to eat it, you would suffer burns before you ever got it in your mouth. You wouldn’t be able to swallow it — lava is molten rock, and as such, is extraordinarily dense and viscous.

According to Wikipedia, the temperature of lava is between 700 and 1200 °C (973 to 1473 K). The melting point of Diamond at about 100,000 atm is 4200 K, which is much higher than the temperature of lava. So, it is impossible for lava to melt a diamond.

Molten rock, known as magma, erupts through fissures in Earth’s crust, becoming lava. If that lava rises above 525 ˚C (977 ˚F), it glows red, with hotter lavas becoming orange or even yellow.১৪ জানু, ২০১৯

The volcano contains large amounts of pure sulfur, which emits an icy violet color as it burns, filling the air with toxic fumes. The picture above was taken in a low lying field in Ethiopia. So what we’re seeing here is not actually blue lava, but normal, bright purple lava, surrounded by blue flames.১ ফেব, ২০২১

The sun is much hotter than lava. Surface temparature of the sun is 10,000 degrees F, while Lava averages only 2000 degrees F. Lava’s temperature is between 700 to 1200 degrees Celsius and the surface of the sun is around 10,000 degrees celsius. That’s about five times hotter than the hottest lava on Earth.

Most lava is very hot—about 2,000 degrees Fahrenheit. At those temperatures, a human would probably burst into flames and either get extremely serious burns or die. Unlike a lake, people won’t immediately sink into lava.৯ নভেম্বর, ২০১৭

High enough heat will indeed burn bone. Anything living that has bones would certainly be destroyed by lava.৬ এপ্রিল, ২০১৯

You get burned, because lava has a really high temperature. Now if you touch it through an insulator, it’s still really hot but you might not get burned if you pull away fast enough. The lava is kind of viscous, so it’d be like stepping on really springy play dough. Really hot springy play dough.

The most familiarly occurring smell is that of sulphur, simply because it is the strongest. In itself, lava (i.e. molten or solidified rock) is mostly totally odourless to humans.১৪ এপ্রিল, ২০০৯

Leifer — who explained ocean entries of lava are extremely explosive and dangerous — does not recommend people get too close to the volcanic flow. “The primary problem is the instability of the surrounding cliffs, since they collapse occasionally.৬ মার্চ, ২০১৭
