GCSE Physics - The Life Cycle Of Stars / How Stars are Formed and Destroyed #84

The video explains the lifecycle of stars, starting from a nebula, forming a protostar, and transitioning into a main sequence star through nuclear fusion. As stars exhaust their hydrogen, they evolve into red giants or red super giants, depending on their size. Red giants shed their outer layers to become white dwarfs, eventually cooling into black dwarfs. Red super giants undergo supernova explosions, forming neutron stars or black holes. The video concludes with a recap of these processes.

What is the initial stage of a star's formation called?

Describe the process that occurs when the temperature and pressure in a protostar become high enough.

What happens to a star when it exhausts its hydrogen supply?

Explain the difference between a red giant and a red super giant.

What is a white dwarf and how does it form?

What occurs during a supernova and what elements are formed?

What are the possible outcomes for a star after it has gone through a supernova?
