What is the critical temperature the core must reach for a star to shine by fusion?
about 10500-11000k is when fusion commences which creates the shining of the star
What is the heat and energy of a star is generated by?
The energy in a star is generated by nuclear fusion.
Why does a star produce light?
Because of nuclear fusion! The nuclear fusion releases energy which produces light.
What are two competing forces in a star?
Gravity and Fusion.
What gives a star its energy?
Nuclear fusion.
What creates the heat and light in a star?
Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.
When a protostar rises to 10000000 degrees celsius will a protostar become a star before or after nuclear fusion?
through the process of fusion, it becomes a star: the birth of the star is the start of fusion. therefore, it is after fusion that it is classified as a star.
What is a star that expands due to fusion?
A star that expands is running low on fuel, and is entering its end-of-life sequence. Its not due to fusion - all stars use fusion.
When its fusion stops a star will become either a black hole a neutron star or?
When fusion stops in a star it will start to fuse helium and will become a red giant.
How is nuclear fusion in a main-sequence star is different from nuclear fusion in a giant star.?
Nuclear Fusion in a Giant Star involves Helium being fused into a hydrogen shell that surrounds the core, and Nuclear Fusion in a Main-Sequence star involves Hydrogen being fused into Helium to produce Energy inside of the core.
Does hydrogen fusion occur in the corona?
No. Hydrogen fusion occurs in the star's core.
How does a star get energy?
nuclear fusion
What is the critical temperature the core must reach for a star to shine by fusion?
about 10500-11000k is when fusion commences which creates the shining of the star
What star is so small in mass that its core never gets hot enough to sustain nuclear fusion reactions?
It isn't a star unless it can sustain fusion. We might call such an object a "failed star", but unless it can sustain fusion it isn't a star at all.
What produces a star's energy?
The nuclear fusion that goes on within the star.
Where would you find a nuclear fusion reaction occurring?
You can find nuclear fusion in a star.
What is the difference between a fusion reactor and a star?
Basically size. A star is massive and fusion reactions are sustained for billions of years. We have a few experimental fusion research tokomaks and fusion has only been maintained for a few seconds. We have a long way to go before fusion powers our homes
