Question

Where does fusion regularly occur and what kind of energy is produced?

A. Fusion occurs inside the sun. It creates the light and heat that sustain life on Earth.

B. Fusion occurs in a nuclear power plant. The energy produced is light and heat.

C. When wood burns, fusion occurs. The energy produced is light and heat.

D. Fusion occurs inside the Earth. It heats magma, which can then be used to heat homes or generate electricity.

a:Fusion occurs inside the sun. It creates the light and heat that sustain life on Earth.

Answer 2

Answer: A. Fusion occurs inside the sun. It creates the light and heat that sustain life on Earth.

Explanation:- Nuclear fusion is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of thermal energy.

The process involves the following reactions:
`_1^1\textrm{H}+_1^1\textrm{H}\rightarrow 1^2\textrm{H}+_(+1)^0\textrm{e}+\text{energy}`

`_1^2\textrm{H}+_1^1\textrm{H}\rightarrow2^3\textrm{He}+\text{energy}`

`_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_(+1)^0\textrm{e}+\text{energy}`

Overall reaction for the above series of reactions is given by:

`4_1^1\textrm{H}\rightarrow_2^4\textrm{He}+2_(+1)^0\textrm{e}+\text{energy}`
