Concept explainers
(a)
Interpretation:
To analyse whether the given statement −In nuclear fusion, two nuclei combine to form a new nucleus, is true or not.
Concept Introduction:
When two or more than two nuclei join, they form a different nucleus with protons and neutrons and it is known as nuclear fusion.
(b)
Interpretation:
To analyse whether the given statement −The energy of the sun is derived from the fusion of two hydrogen-1
Concept Introduction:
When two or more than two nuclei join, they form a different nucleus with protons and neutrons and it is known as nuclear fusion.
(c)
Interpretation:
To analyse whether the given statement −The energy of the sun occurs because once two hydrogen nuclei fuse, the two positive charges no longer repel each other, is true or not.
Concept Introduction:
When two or more than two nuclei join, they form a different nucleus with protons and neutrons and it is known as nuclear fusion.
(d)
Interpretation:
To analyse whether the given statement −Fusion of hydrogen nuclei in the sun results in a small decrease in mass, which appears as an equivalent amount of energy, is true or not.
Concept Introduction:
When two or more than two nuclei join, they form a different nucleus with protons and neutrons and it is known as nuclear fusion.
(e)
Interpretation:
To analyse whether the given statement −Einstein’s famous E=mc2 equation refers to the energy released when two particles of the same mass collide with the speed of light, is true or not.
Concept Introduction:
When two or more than two nuclei join, they form a different nucleus with protons and neutrons and it is known as nuclear fusion.
(f)
Interpretation:
To analyse whether the given statement −Nuclear fusion occurs only in the sun, is true or not.
Concept Introduction:
When two or more than two nuclei join, they form a different nucleus with protons and neutrons and it is known as nuclear fusion.
(g)
Interpretation:
To analyse whether the given statement −Nuclear fusion can be carried out and controlled in the lab, is true or not.
Concept Introduction:
When two or more than two nuclei join, they form a different nucleus with protons and neutrons and it is known as nuclear fusion.
