Question

In the process of nuclear fusion:
A) Only heavy nucleus break into light nuclei
B) Fusion of light nuclei at normal temperature takes place
C) Fusion of light nuclei at high pressure and low temperature takes place
D) Fusion of light nuclei at high pressure and high temperature takes place

Answer 1

Hint:It is a Reaction between light elements and heavier elements. It is an exothermic reaction.

Step by Step Solution
Nuclear fusion is a reaction where two atomic nuclei fuse together to create a larger nucleus and in the process release energy. We can imagine a fusion reaction like a vehicle collision we might see on the road. Two vehicles colliding into each other and get stuck permanently together while little pieces of them go flying off in every direction. Nuclear fusion is just like the same where the vehicles are atomic nuclei and the little pieces are various particles and energy released.

So in other words Nuclear fusion is a reaction where two light atomic nuclei combine together to form a single heavy Nuclei, with release in energy.
Also there is coulomb force of repulsion acts between the atoms so it is necessary to carry this reaction at high temperature and pressure which gives the hydrogen atoms enough energy to overcome the electrical repulsion between the protons

Additional information-Currently, there are no large-scale fusion reactors that could provide energy for commercial use. This is because it has been difficult to create a controllable, non-destructive way of storing the energy released during fusion

Note-Every star in the universe, including the sun, is alive due to nuclear fusion. It is through this process that they produce such a mind-boggling amount of heat and energy. The pressure at the core of any star is tremendously high and that is where the nuclear fusion reaction takes place.
