A large cool star formed when a star runs out of hydrogen?
red giant
What is large cool star formed when a star runs out of hydrogen?
A supergiant or red giant. They are normally around 3,500 degrees C and are very bright, near -5 on the Hertzsprung-Russell Diagram. These are the largest stars in the galaxy and universe.
Does nuclear fusion occurs as stars cool down?
The star will continue to fuse hydrogen until it runs out of resources and dies out, after which it will collapse and die.
How does the gas get into the sun?
Initially, 5 billion years ago, a large collection of Hydrogen gas accumulated over time to form a large body of gas. When temperature gets extremely high in the core of this body, nuclear fusion starts, using the gas as fuel. So, there was already gas in the first place, and the star dies when this fuel runs out.
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.

How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
Does nuclear fusion occurs as stars cool down?
The star will continue to fuse hydrogen until it runs out of resources and dies out, after which it will collapse and die.
What is the largest desert that runs along southwestern coast?
The Namib Desert is the large desert on Africa's southwestern coast. It is a cool coastal desert.
Is there a car that runs on water?
They are working on that. They have machines that can separate the hydrogen from the oxygen. An automobile can run on hydrogen.
What is the large desert that runs along southwestern coast?
The Namib Desert is the large desert on Africa's southwestern coast. It is a cool coastal desert.
When a star runs out if hydrogen what does it use as fuel source?
helium
How much water will a car that burns hydrogen exhaust?
if it runs on pure hydrogen then the only exhaust will be pure water vapor.
What is the role of hydrogen in living organisms?
Oxygen burns hydrogen in the living system, releasing the energy that runs living beings.
What is the fuel for stars?
Fusion, 2 hydrogen atoms turning into one Helium atoms continuously. (until the hydrogen runs out)
