Answer 1

Answer:

The nuclear fusion inside the core of star produces vast amount of energy. Nuclear burning (reaction) is much different from burning of simple hydrocarbons (coal, petrol, etc) where small amount of energy is produced. The Hydrogen gas or Helium is burnt as a nuclear fuel inside the star to produce energy.

Answer 2

Star:

• A star is a huge ball of heated gas that is also shining and glowing. Helium is produced when the collision of hydrogen atoms is taken place in a star's core, which also releases a tremendous amount of energy as well as warms the gas.
• A star shines because of a certain process known as nuclear fusion. The force of gravity is resisted when the hot gas pushes outward into the opposition towards it.
• A star is created by the interaction of these forces. For the majority of its existence, it maintains the star's main structure and maintains a constant temperature.
• Stars are born in hefty clouds of gas as well as dust throughout the cosmos. Gas and dust are collected into clumps by means of gravity. A star may arise if the clump has sufficient mass. Nuclear fusion starts when the core ignites due to the rising temperature and pressure.
