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.
The highest temperature ever reached under controlled conditions is an astonishing two billion degrees. It was created in the so-called Z-machine at the Sandia Laboratories, New Mexico, which uses incredibly high electric currents and magnetic fields to release radiation from atoms.
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.
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. On the other hand, a big blob of lava contains many more bouncing particles than a small candle flame, so it has a lot more heat energy.
The Sun does not "burn", like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core.

Io is the most geologically active world in the Solar System, with hundreds of volcanic centres and extensive lava flows. Lava worlds orbiting extremely closely to the parent star may possibly have even more volcanic activity than Io, leading some astronomers to use the term super-Io.
The coldest erupting lava in the world is the natrocarbonatite lava of the volcano Oldoinyo Lengai, Tanzania that erupts at temperatures of 500-600°C (930-1,110 °F).
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.
We conclude that the optimal heat generated by lava at 2,190°F cannot melt the tungsten because of its high melting point. Other examples of metals and ceramics that can withstand lava's temperature include; titanium, iridium, iron alloys, osmium, nickel alloys, aluminum oxide, mullite, and silicon nitride.
Dipping your hand into molten rock won't kill you instantly, but it will give you severe, painful burns — “the kind that destroy nerve endings and boil subcutaneous fat,” says David Damby, a research chemist at the USGS Volcano Science Center, in an email to The Verge.
Geologist say, the drill bit used to hammer the rock into pieces, gets hot from the solidified lava, which is still at 752 degrees Fahrenheit, occasionally causing the bit to turn purple from the intense heat.
The answer lies in how you define “wet”. If we're using it as an adjective (definition: covered or saturated with water or another liquid), then lava is a liquid state so it therefore it's wet. But nothing touched by lava is left damp or moist, which means that you can't really use wet as a verb to describe lava.
Laser experiments shedding light on ultradense plasma. To the researchers, though, the cosmic-level heat wasn't a goal but a side effect.
Steel melts around 1,300 degrees, so the metal body likely melted and mixed with the lava while everything else in the car would have burned up as the lava passed over it. Even if it doesn't completely melt, it will be encased in volcanic rock when things are all said and done.
Although the temperature of water immediately adjacent to the submarine lava reaches 88 degrees C (190 degrees F), it degrades quickly to 27 degrees C (81 degrees F), only slightly above the ambient ocean temperature, within a few inches of the contact.
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.
Does lava instantly melt you if you touch it? You would likely burst into flames on a close approach, actually. But yes, you would 'melt', but we would call it 'burning'. However, skin does melt, and so will your bones.
The more massive a black hole, the colder it is. Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius.
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.
Space scientists have discovered the hottest place known in the Universe where temperatures reach an amazing 300 million degrees C. A cloud of searing gas is surrounding a swarm of galaxies clustered together five billion light-years away in the constellation of Virgo.
Over the past 4.5 billion years, the Sun has gotten hotter, but also less massive. The solar wind, as we measure it today, is roughly constant over time. There are the occasional flares and mass ejections, but they barely factor into the Sun's overall rate at which it loses mass.
Concrete has a melting point of about 1,500 degrees Celsius (2,700 degrees Fahrenheit), while lava reaches a piddly 871 degrees Celsius (1,600 degrees Fahrenheit). Pour enough concrete into a vent and you would theoretically be able to block it.
