Answer:
Sequence of stages of star formation:-
1. A ball of hot air is formed
2. Temperature and density increases
3. Atomic energy generation
4. The sphere of air is self-illuminated.
Explanation:
Stages of star formation:-
(1.) Giant Gas Cloud:- A star originates as a collection of large clouds of gas. Since the temperature of the cloud is low for the nuclear synthesis, so they undergo further processes.
(2.) Protostar:- All the surrounding particles and molecules accumulate at the center of the cloud under the gravitational pull. The mass of star keeps on increasing and the temperature increases as well.
(3.) A T-Tauri Phase starts when materials stop falling in the core of the cloud and release a lot of energy.
(4.)Main Sequence Stage:- In this stage is nuclear fusion occurs and atomic energy generation. When two hydrogen atoms undergo nuclear fusion, they generate helium. This reaction is exothermic. The star begins to release energy, and causes it to shine or self-illuminated.
