SOLAR SYSTEM

Detailed explanation-1: -In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

Detailed explanation-2: -Answer and Explanation: The very high temperature and pressure in the sun’s core allows the nuclear reaction fusion to occur.

Detailed explanation-3: -Fusion reactions take place in a state of matter called plasma-a hot, charged gas made of positive ions and free-moving electrons with unique properties distinct from solids, liquids or gases. The sun, along with all other stars, is powered by this reaction.

Detailed explanation-4: -Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy-several times greater than fission.
