What happens when magnisium burns?
Magnisium burns with a very bright spark, when its finished burning the magnisium goes all crumy and grey.
When does fusion of hydrogen atoms happens?
under extreme heat and pressure - it happens on the sun all the time!
What happens when hydrogen peroxide is mixed with raw steak?
i think all the blood will disappear
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.
All the iron molecules that are in our body were originally created by?
An exploding (at the end of its life) star. Same for all the other atoms - except hydrogen.
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 causes a red 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.
Can the sun melt?
No. The sun burns its hydrogen and will eventually use up all its fuel. The Sun is a name of the Star in our galaxy. There are two ways a star will die out. Some Stars will bascially explode. Others will cool and contract to a small, dense star. They do not melt.
What would happen if all of the hydrogen in the sun turned into helium?
The way a star burns it's fuel does in fact change it. The star will die when the fuel becomes too dense depending on the size of the star. For instance, if our sun was full of lead, it would explode, and we would cease to exist.
What happens during the third stage of a stars life cycle as the star uses up all of its hydrogen?
The core of a star contracts under the force of its own gravity. This contraction increases the temperature in the core.
What happens when all 3 isotopes of hydrogen react with chlorine in sunlight?
It forms hydrogen chloride
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 when magnisium burns?
Magnisium burns with a very bright spark, when its finished burning the magnisium goes all crumy and grey.
What type of star used up all of its hydrogen and its leftover center of an older star?
this is called a white dwarf
