When a main sequence star, such as our sun, exhausts it's supply of Hydrogen, fusion of Hydrogen to Helium ceases in the core. This results in cooling of the core and therefore causes it to contract. As the core contracts, the layers surrounding the star gain kinetic energy until the fusion of Hydrogen is possible in the outer layers. As these layers undergo fusion, they increase in temperature dramatically. The outer layers expand due to heat, and the star becomes massive; the main sequence star has evolved into a red giant. Fusion of Hydrogen to Helium continues in the outer layers, whilst the fusion of heavier elements such as carbon occurs in the core.
What else can I help you with?
A young star has a large supply of what to fuel its inner fires?
hydrogen
What triggers a super nova?
When its original source of fuel has run out for instance our sun runs on hydrogen, after the depletion of the original fuel is gone the suns core condenses creating helium were the star expands to great measures were it gets to a size were its limited supply of helium runs out either collapsing into a black hole or a dwarf star
If a cell did not have a supply of amino acids what could happen?
No proteins.
What are the stages of a medium sized main sequence star?
A medium-sized main sequence star, like our Sun, goes through several stages in its life cycle. It starts as a protostar, forming from a cloud of gas and dust, and then enters the main sequence phase where it fuses hydrogen into helium in its core, maintaining stability for billions of years. Once it exhausts its hydrogen supply, it evolves into a red giant, eventually shedding its outer layers to create a planetary nebula. The remaining core then becomes a white dwarf, which will gradually cool and fade over time.
What does a quasar evolve into?
A quasar evolves into a galaxy as it exhausts its fuel supply of supermassive black holes at its core. Once the black hole stops accreting matter and emitting large amounts of energy, the quasar phase ends, and it becomes a mature galaxy.
How many more years worth of hydrogen does the sun have left?
The sun has about 5 billion years worth of hydrogen left before it exhausts its supply and evolves into a red giant star.
Why does the amount of hydrogen in a star decrease?
The amount of hydrogen in a star decreases over time because hydrogen fuses into helium through nuclear reactions in the star's core, releasing energy in the process. As the star continues burning hydrogen, it eventually exhausts its hydrogen fuel supply, leading to changes in its structure and behavior.
A cell has enough available ATP to meet its needs for about 30 seconds What is likely to happen when an athlete exhausts his or her ATP supply?
When an athlete exhausts his ATP supply, catabolic processes are activated so that it will generate ATP. The function of ATP in the cell is the transportation of chemical energy used in metabolism.
A star that is a has exhausted its supply of hydrogen?
A star that is a white dwarf has exhausted its supply of hydrogen.
Hypothesize why the uterine lining thickens and it's blood supply increases during each menstrual cycle?
The uterus is preparing for the possible fetus.
What would happen to supply if demand when up?
supply will increase.
If the price of resources increases what will happen to supply?
supply will decrease
What is it called that has exhausted it's supply of hydrogen?
A star that has exhausted the hydrogen in its core will become a red giant or supergiant.
What forces cause the expansion of the sun as it burns off its fuel?
The expansion of the Sun as it burns off its fuel is primarily driven by the balance between gravitational forces and the pressure generated by nuclear fusion in its core. As hydrogen is converted into helium through fusion, energy is released, creating outward pressure that counteracts gravitational collapse. Over time, as the hydrogen fuel diminishes, the core contracts and heats up, leading to increased fusion rates and causing the outer layers to expand. This process results in the Sun eventually becoming a red giant as it exhausts its hydrogen supply.
A young star has a large supply of what to fuel its inner fires?
hydrogen
Where can you buy hydrogen in the UK?
From any reputable chemical supply company !
What will a star become as it uses up its hydrogen supply?
a super giant.
