Answer 1

Explanation:

Nuclear Fusion in Stars

Ancient astronomers thought that the Sun was a ball of fire, but now astronomers know that it’s nuclear fusion going on in the core of stars that allows them to output so much energy. Let’s take a look at the conditions necessary to create nuclear fusion in stars and some of the different kids of fusion that can go on.

The core of a star is an intense environment. The pressures are enormous, and the temperatures can be greater than 15 million Kelvin. But this is the kind of conditions you need for nuclear fusion to take place. Once these conditions are reached in the core of a star, nuclear fusion converts hydrogen atoms into helium atoms through a multi-stage process.

Answer 2

Answer:

hey dear...

.Stars run on a Nuclear fission because their immense size and gravity creates the incredible pressures needed to Kickstart the fission of Hydrogen in helium.once this reaction start,the heat and pressure increases and the reaction become self - sustaining,rapidly creating heavier atoms from lighter ones.
