Question

Fusion reaction takes place at high temperature because

• A. nuclei break up at high temperature
• B. atoms get ionised at high temperature
• C. kinetic energy is high enough to overcome the coulomb repulsion between nuclei
• D. molecules break up at high temperature

Hint:

In order to overcome the coulomb repulsion between nuclei as two lighter nuclei join to produce a heavier nucleus, high temperature, and high pressure are necessary.

Answer 1

The Correct Option is C

Coulomb resistance between nuclei can be overcome because of the large kinetic energy.

In order to overcome the coulomb repulsion between nuclei as two lighter nuclei join to produce a heavier nucleus, high temperature, and high pressure are necessary.

Real Life Applications

• The nuclear power plant that uses fusion reactions to generate electricity.
• Fusion reactions could be used to power spacecraft.
• Fusion reactions could be used to produce medical isotopes, Fusion reactions could also be used to create new drugs and treatments.
• The fusion reaction used to form nuclear power creates a form of clean energy.

Answer 3

The Correct Answer is (C)

Protons are positively charged particles that are found in atoms among other things. 

• Protons in an atom stick together because of a strong interaction that pulls them near to one another.
• As known, particles with the same electromagnetic charge repel one another.
• In order to fuse the two atom nuclei in the fusion process, one must first get them close together before considering a possible reaction.
• Given that both atomic nuclei have positive charges, it follows that they will repel one another.
• Now, the reaction will happen if one gives them a high temperature.
• Due to the strong interaction pulling the protons together is stronger than the repulsion pushing the protons apart at high temperatures, the atoms will fuse together to form a new atom that contains protons from both of the atoms we pushed together.

Nuclear Fusion

Atomic combination is the process of fusing together two smaller, lighter cores to form a larger core.

• The helium core (²He₄) is formed as a result of the intertwining of three deuteron cores (¹H₂) and the delivery of 21.6 MeV of energy.
• There is a lot of energy exchanged in this contact.
• Atomic fusion occurs at a very high pressure of 106 atmospheres and a very high temperature of around 107 K.
• Atomic combination is necessary for a nuclear weapon.
• The atomic combination that occurs at the sun is the source of all of its energy.
