Is the Sun a nuclear explosion?
The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 500 million metric tons of hydrogen each second.
How hot was the atomic bomb compared to the Sun?
A primary form of energy from a nuclear explosion is thermal radiation. Initially, most of this energy goes into heating the bomb materials and the air in the vicinity of the blast. Temperatures of a nuclear explosion reach those in the interior of the sun, about 100,000,000° Celsius, and produce a brilliant fireball.
How many atomic bombs equal the Sun?
We get the astonishingly huge amount of 400 trillion trillion watts. To put this into a crazy context, every second the sun produces the same energy as about a trillion 1 megaton bombs! In one second, our sun produces enough energy for almost 500,000 years of the current needs of our so-called civilization.
How does the Sun do nuclear fusion?
The Sun shines because it is able to convert energy from gravity into light. This is what happens to the hydrogen gas in the core of the Sun. It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion.
What is the fireball of a nuclear bomb?
The fireball, an extremely hot and highly luminous spherical mass of air and gaseous weapon residues, occurs within less than one millionth of one second of the weapon’s detonation. Immediately after its formation, the fireball begins to grow in size, engulfing the surrounding air.
How are nuclear reactions different from chemical reactions?
Nuclear reactions involve a change in an atom’s nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
What is the overall fusion reaction by which the Sun currently produces?
The overall fusion reaction by which the Sun currently produces energy is E) 4 H ⇒ 1 He + energy. Why must the Sun’s rate of fusion gradually rise over billions of years?
What is the energy of a thermonuclear explosion?
The fireball and thermal pulse emitted by a thermonuclear explosion represents the most concentrated burst of energy that has ever occurred on planet Earth. In fact, the magnitude of light emission can be many times greater than the light emitted from a corresponding area on the sun’s surface.
What happens first when a nuclear explosion explodes?
Although the formation of a mushroom cloud has become the most recognizable feature of a nuclear explosion (see previous section), it is actually not the generation of smoke that happens first, but the release and propagation of a wave of blinding light and intense heat energy.
What happens when a thermonuclear bomb hits the Earth?
The blast of a thermonuclear device is like suddenly having a piece of a supernova appear on the Earth. It causes an explosive discharge of heat in an expanding fireball and thermal pulse that destroys everything in it path—vaporizing anything nearby and instantly igniting combustible materials much farther away from the fireball core.
