What Is Nuclear Fusion? | The Solar Energy Song | KLT

The video explains the process of nuclear fusion in the sun's core, where hydrogen atoms fuse under immense pressure and gravity to form helium, releasing energy. This energy production process is crucial for the sun's stability, maintaining hydrostatic equilibrium. The sun converts millions of tons of hydrogen into helium every second, with some mass converted into energy that counteracts gravitational forces.

What is the primary composition of the sun's core?

• Carbon atoms

• Oxygen atoms

• Hydrogen atoms

• Helium atoms

What force is responsible for squeezing the sun's core and enabling nuclear fusion?

• Gravitational force

• Centrifugal force

• Nuclear force

• Electromagnetic force

How many hydrogen atoms are fused to form one helium atom in the sun?

• Five

• Four

• Three

• Two

What happens to the remaining protons after the formation of a helium nucleus?

• They are absorbed by the sun

• They create photons and release energy

• They remain in the sun's core

• They form new hydrogen atoms

What is the term for the balance between the outward pressure and gravitational force in the sun?

• Hydrostatic equilibrium

• Dynamic equilibrium

• Thermal equilibrium

• Chemical equilibrium
