What color is the sun?
But, as can be seen in the image above, it emits most of its energy around 500 nm, which is close to blue-green light.
So one might say that the sun is blue-green.
This maximum radiation frequency is governed by the sun’s surface temperature, around 5,800K..
Can fire burn underwater?
Combustion needs oxygen to take place, if you provide an oxygen source by chemical or mechanical means, fire can burn underwater. A chemical reaction that gives up a lot of heat may stay burning for a little bit, but remember water has a high heat capacity and would cold the reaction quite fast.
Is fire possible in space?
In space, of course, you can’t have any fires because there isn’t any oxidizer (i.e. oxygen) to sustain the combustion process. … In space, of course, you can’t have any fires because there isn’t any oxidizer (i.e. oxygen) to sustain the combustion process.
What color is the sun green?
When we see the Sun at sunrise or sunset, when it is low in the sky, it may appear yellow, orange, or red. But that is only because its short-wavelength colors (green, blue, violet) are scattered out by the Earth’s atmosphere, much like small waves are dispersed by big rocks along the shore.
Is there still undiscovered gold?
The USGS reports that about 18,000 tonnes of gold remain undiscovered in the U.S., with another 15,000 tonnes having been identified but not mined. … In 2018, mines in the Silver State produced 173.6 metric tons of gold, along with 249.2 metric tons of silver, according to the Nevada Mining Association.
What holds the sun in place?
gravityOn this page. The Sun is a yellow dwarf star, a hot ball of glowing gases at the heart of our solar system. Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest particles of debris – in its orbit.
Is there gold on the sun?
Careful analysis of the Sun’s spectrum shows that about 6 ten-billionths (0.0000000006) of the mass of the Sun consists of atoms of gold. Doesn’t sound like much does it? But, because the Sun is so huge, this is a lot of gold!
How does the sun work?
In the core of the Sun, hydrogen turns into helium and causes a fusion – which moves to the surface of the Sun, escaping into space as electromagnetic radiation, a blinding light, and incredible levels of solar heat. …
Does the sun have lava?
Many people immediately think of lava, the hot, molten rock that occasionally flows from volcanoes. Lava is indeed very hot, reaching temperatures of 2,200° F or more. … 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.
Is Sun have oxygen?
The sun, like the rest of the universe, is made mostly of hydrogen. There isn’t enough oxygen in the entire solar system to keep the surface of the sun burning through chemical combustion for more than a very short time—probably hours. Instead, the sun’s heat and light comes from thermonuclear fusion.
Is the sun White?
Around sunrise and sunset, when the sunlight travels through a lot more atmosphere than usual, sunlight on earth’s surface becomes even more red. But the sun itself is white. Sunlight spectrum in space as a function of wavelength.
What color is the hottest star?
blueThe color of a star is linked to its surface temperature. The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.
What year will the Sun die?
What will happen when the sun dies? But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the birth of our solar system, about 4.5 billion years ago.
Is the sun made of fire?
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. … Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!
What is hotter than the sun?
Yep, the answer is a bolt of lightning. What’s five times hotter than the sun and capable of sending a DeLorean back to the future? Yep, the answer is a bolt of lightning, which can reach temperatures of roughly 30,000 kelvins (53,540 degrees Fahrenheit).
Is there gold on the moon?
There is water on the moon … along with a long list of other compounds, including, mercury, gold and silver. That’s according to a more detailed analysis of the chilled lunar soil near the moon’s South Pole, released as six papers by a large team of scientists in the journal, Science Thursday.
What is the heaviest element Our sun will ever create?
The sun currently fuses hydrogen into helium. … Eventually, slow fusion of the heliun and carbon will cause the dying sun to produce its heaviest element: oxygen. … Heavier and larger stars may fuse the carbon into oxygen, and so on until they start producing iron.More items…
Is lava hotter than fire?
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.
What is the hottest lava on Earth?
Bright red lava flows in Hawaii can get as hot as 1,165 F, with the glowing orange flows getting hotter than 1,600 F, according to USGS. And when rock is seriously melting, such as the magma within the Hawaiian volcano of Kilauea , it can reach 2,120 F, according to USGS.
Can we survive without sun?
Without the Sun’s rays, all photosynthesis on Earth would stop. … While some inventive humans might be able to survive on a Sun-less Earth for several days, months, or even years, life without the Sun would eventually prove to be impossible to maintain on Earth.
What is the sun made up of?
hydrogenJust like most other stars, the sun is made up mostly of hydrogen, followed by helium. Nearly all the remaining matter consists of seven other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon.
