What are the major sources of C in our atmosphere?
How long does co2 remain in the atmosphere
Is the sun breaking apart?
No, the sun is not breaking apart. It is a stable star that is undergoing nuclear fusion in its core, converting hydrogen into helium and releasing energy in the process. The sun is expected to remain stable for billions of years to come.
What makes a star?
A star is made up of mostly hydrogen and helium gas, which undergoes nuclear fusion in its core, releasing energy in the form of light and heat. This fusion process creates a delicate balance between the inward force of gravity and the outward force of radiation pressure, enabling the star to shine and remain in a stable state for millions to billions of years.
How long will the star vega live?
Vega is a relatively young star with an estimated age of around 455 million years. It is currently in the main sequence stage of its life, where it fuses hydrogen into helium in its core. It is expected to remain in this phase for several billion years before eventually evolving into a red giant.
How do large mass star stay in the main sequence?
The "main sequence" basically consists of all those stars that fuse hydrogen-1, converting it into helium-4. A massive star will remain in the main sequence while it has enough hydrogen-1; but since it gets hotter and burns its fuel much faster, it may stay there only for a fairly short time - in the case of the most massive stars, just a few million years.
Does the amount of hydrogen in the atmosphere remain constant?
Hydrogen rises above our atmosphere to the outer limit and then gets blown away by 'solar wind'. So it is decreasing.
Does steam from hot water create hydrogen for a helium balloon?
No. Steam is simply water in a gaseous state. The hydrogen and oxygen remain chemically bonded to one another.
What heavier element is created when hydrogen atoms fuse together in the suns core?
Normal "main sequence" stars fuse hydrogen into helium during most of the star's life. The core of a star gets so hot that the hydrogen atoms begin to fuse together. As hydrogen only has 1 proton when if fuses with another hydrogen atom it has 2 protons so has become helium.
What is the sun formed out of?
The Sun is made up mainly of hydrogen, less helium, and small amounts of heavier elements. Four hydrogen atoms fuse to from one helium atom, in this process a lot of energy & heat is released. The sun will remain stable until the whole hydrogen is converted into helium. When the total hydrogen is exhausted energy production stops in its core and thus the core starts shrinking.
How would earths atmosphere be different if organisms capable of photosynthesis not evolved?
It will remain as reductive atmosphere. Ther will be only gases like NH3, H2 , H2S. H2O. There would be no life
If liquid nitrogen freezes everything why is itself a liquid?
liquid nitrogen will not freeze everything. Hydrogen and helium will remain a gas when exposed to liquid nitrogen.
What rock is Sun made from?
The sun is not made of rock. It is made mostly of the gasses hydrogen and helium. The sun is far too hot for anything to remain solid.
The last two elements that a massive star produces are hydrogen and helium why is this the last reaction?
Hydrogen and helium are the lightest and most abundant elements in the universe. In the core of a massive star undergoing nuclear fusion, hydrogen and helium are fused into heavier elements like carbon, oxygen, and iron. Once the star reaches the stage where it can no longer sustain fusion reactions to produce heavier elements, hydrogen and helium remain as the last elements in its core before it undergoes a supernova explosion.
Are the sun and other stars made out of rocks and ice?
No. Stars are made mostly of hydrogen and helium and are too hot for any sort of rock or ice to remain solid.
What will the helium become when it grows up?
Helium will remain helium as it does not undergo transformation or maturation into a different element. Helium is a noble gas and one of the most stable elements, maintaining its properties throughout its existence.
Are all the hydrogen of ethyl chloride equivalent?
Hydrogen remain hydrogen.
