What else can I help you with?
What is the heat and energy of a star is generated by?
The energy in a star is generated by nuclear fusion.
What event marks the birth of a star?
fusion of hydrogen atoms into helium atoms
Why does a star produce light?
Because of nuclear fusion! The nuclear fusion releases energy which produces light.
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.
Which process produces the energy radiated by the star when it become a main sequence star?
nucleur 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.
Which nuclear fusion cycle is the next one to begin after helium fusion ends in a massive star?
The next nuclear fusion cycle after helium fusion in a massive star is carbon fusion. This process involves fusing helium nuclei to form carbon. Carbon fusion typically occurs in the core of a massive star after helium fusion is completed.
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 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.
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.
What produces a star's energy?
The nuclear fusion that goes on within the star.
The onset of iron fusion causes a star to become a?
The onset of iron fusion causes a star to become a supernova. This process occurs when the star's core collapses due to the inability to support the fusion of iron, leading to a catastrophic explosion.
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.
Why can iron fusion not support a star because of iron?
Iron fusion cannot support a star because iron is the most stable element and cannot release energy through fusion reactions. This causes the star to collapse, leading to a supernova explosion.
How does a star create such energy?
nuclear fusion
What makes a star glow?
nuclear fusion
