When does fusion of hydrogen atoms happens?
Fusion of hydrogen atoms occurs in the core of stars, where intense heat and pressure cause hydrogen nuclei to merge and form helium. This process releases energy in the form of light and heat, providing the source of a star's power.
If a star becomes a red gaint when all its hydrogen is used up and later becomes a nebula How can a nebula star form without hydrogen?
The key to this is that NO star uses up ALL of its hydrogen. In fact, they only use up the Hydrogen in their cores, where pressure and temperature are highest. In the case of a red giant, the star is at the stage of burning Helium into Beryllium, Boron and Carbon, which requires much more heat (the heat is "borrowed" from the previous collapsing of the star at the end of the main sequence phase) and continues with a much denser core. When a star expands into a red giant, it blows some of its Hydrogen mass into space. Later, when it simply cannot sustain any fusion reactions in its core, it still contains a considerable amount of hydrogen in the outermost layers, and the subsequent collapse causes a rebound (supernova) that blows about 50% of the original star's mass - most of the hydrogen plus some of the heavier elements into space. When that blown away material collides with a large gas cloud in space which is mostly hydrogen, and compresses that cloud enough that the material can then collapse and form another new star.
What happens when hydrogen burns with oxygen to make water?
When hydrogen burns with oxygen to make water, a chemical reaction occurs where hydrogen atoms combine with oxygen atoms to form water molecules (H2O). This reaction releases energy in the form of heat and light, which is why it is called a combustion reaction. The balanced chemical equation for this reaction is 2H2 + O2 -> 2H2O.
What metal burns in water?
sodium, potassium, rubidiumSodium reacts very quickly with water. All Alkali metals, the first column of the periodic table excluding Hydrogen (H), react violently with water. The lower the row, the more explosive the reaction.
Will hydrogen peroxide burn your face?
Pure hydrogen peroxide certainly can cause chemical burns if it touches your skin. Hydrogen peroxide you buy from a drugstore is typically about 3% hydrogen peroxide and 97% water. As far as your skin is concerned, as long as you're not actually bathing in it it's not all that different from 100% water. You should be careful with even the dilute stuff around your eyes and mouth though; the mucous membranes are much more sensitive.
What happens when a star burns all of its hydrogen?
When a star burns up all of its hydrogen,it becomes red in color.As hydrogen is the fuel for star and it will burst after it.
What causes a giant?
After a star burns up all it's hydrogen, it becomes a red giant.
What is the main source of energy of a star as it grows in size to becomes a red giant?
A main sequence star burns hydrogen to helium. Once a main sequence star exhausts all of the hydrogen, it begins to expand and burn helium causing if to become a red giant.
What does a star do in outer space?
A star in outer space burns hydrogen. Some of the stars that we see are already all burnt up and no longer shining, this is because it takes so long for the sight of light to make it to us.
What causes a red giant?
A red giant is caused by the expansion and cooling of a star as it exhausts its core hydrogen fuel and begins to burn helium. This expansion occurs because the core contracts, increasing the temperature and pressure in the outer layers, leading to their expansion and the star's overall growth in size.
When does fusion of hydrogen atoms happens?
Fusion of hydrogen atoms occurs in the core of stars, where intense heat and pressure cause hydrogen nuclei to merge and form helium. This process releases energy in the form of light and heat, providing the source of a star's power.
When a low mass star first runs short of hydrogen in its core it becomes brighter because?
Low mass stars become brighter after depleting hydrogen because all of the hydrogen in the core has been fused into helium. Once this happens, hydrogen fusion begins in the outer layers, which causes more heat and light generation.
What happens to a star when hydrogen burns out?
The star first expands into a red giant (or a supergiant star if the original star was a giant star) and then explodes in a fusion flash (sun-size star), nova (slightly larger), or supernova (for a supergiant).
What type of star used up all of its hydrogen and its leftover center of an older star?
this is called a white dwarf
When all the gases are gone what happens to a star?
first of all, all the gases from the star can't be vanished as this is a scientific reason.
What happens when you become a all-star action all-star?
ok so when you become a all star in action allstars you get a free mvp membership for a month
What happens what a star has lost all of its hydrogen?
When a star exhausts its hydrogen fuel, it can no longer sustain the nuclear fusion processes that power it. As a result, the core contracts and heats up, eventually leading to the fusion of heavier elements like helium. This causes the outer layers of the star to expand, transforming it into a red giant. Eventually, the star may shed its outer layers, resulting in a planetary nebula, while the core remains as a white dwarf.
