Does nuclear fusion happen in the convection zone?
No, nuclear fusion does not occur in the convection zone of a star. Fusion reactions primarily take place in the core region of a star, where the temperature and pressure are high enough to sustain the nuclear reactions that power the star. The convection zone is a region of the star where heat is transported through the movement of gas, but fusion does not occur there.
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 does helium fusion begin in a star?
Hydrogen undergoes nuclear fusion to form helium at a temperature of 107 K
Two main forces in a star?
The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
When a protostar rises to 10000000 degrees celsius will a protostar become a star before or after nuclear fusion?
A protostar must reach about 10 million degrees Celsius for nuclear fusion to start in its core, triggering the transition into a true star. This marks the point where hydrogen atoms begin fusing into helium, releasing energy in the process. So, a protostar will become a full-fledged star after nuclear fusion begins at this temperature.
What happen in the core that marks the birth of a star?
Nuclear fusion, converting hydrogen nuclei into helium nuclei.
How does a star get energy?
nuclear fusion
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.
In which part of a newborn star does the fusion reactio occur?
In a newborn star, the fusion reactions occur primarily in its core, where the temperature and pressure are high enough to trigger nuclear fusion. This process generates the energy that powers the star and allows it to shine bright.
What is the critical temperature the core must reach for a star to shine by fusion?
The critical temperature for nuclear fusion in a star's core is around 10 million degrees Celsius. At this temperature, hydrogen nuclei can overcome their mutual repulsion and fuse to form helium, releasing energy in the process. This energy production is what causes a star to shine.
How nuclear fusion in a main sequence 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.
Where does a star get its energy?
By converting hydrogen to helium using nuclear fusion
