Q. Consider the following statements regarding “Nuclear Fusion”:
1.It is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
2.It takes place in a state of matter called plasma.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C
Notes:

Explanation: Nuclear fusion is the process by which two light atomic nuclei (for example tritium and deuterium) combine to form a single heavier (Helium) one while releasing massive amounts of energy.

  • 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.
  • Strong repulsive electrostatic forces between the positively charged nuclei prevent them from getting close enough together to collide and for fusion to occur.
