Answer the follow

Answer :

Three end stages of stars are:


1. White Dwarf


2. Neutrons Star


3. Black Hole


When the energy generation by the fuel stops then the temperature of the star decreases. Decrease in temperature further leads to decrease in gas pressure. When gravitational force becomes more than gas pressure the star contracts.


Since the size of star decreases, hence its density increases. Due to this, new pressures are generated that don’t depend on temperature. The star becomes stable and the stage is called end stage of star.


End stage depends on the mas of the star.


= Mass of Star



White Dwarf: In this stage the star looks white and due to its small size it is called White Dwarf.


Neutron Star: In this stage star is made up of neutrons completely. The pressure of neutrons are independent of temperature and balance gravitation completely.


Black Hole: In this stage objects are attracted towards the star due to tremendous increase in gravitational force. All lights gets absorbed inside the star.
