Question

explain nuclear fusion and nuclear fission​

Answer 1

Answer:

Nuclear fusion - when two nuclei of light elements combine to form a tremendous amount of energy is called nuclear fusion.

Nuclear fission - the process in which the heavy nucleus of a radioactive atom split up into smaller nuclei when a bombarded with low energy neutron is called nuclear fission. ✔ ✔ ✔

Answer 2

Answer:

$\huge\bold\red{Nuclear}$

$\huge\bold\pink{fission}$

1. In fission when neutrons are bombarded on a heavy nucleus,it splits in 2 nearly equal light fragments.
2. This reaction is possible at ordinary temperature and ordinary pressure.
3. For the same mass,the energy released in the fission process is less than that in the fussion process.
4. Limited amount of fissionable substance is available in nature.

$\huge\bold\blue{Nuclear}$

$\huge\bold\green{fusion}$

1. In fusion,at a very high temperature and high pressure 2 light nuclei combine to form a heavy nucleus.
2. This reaction is possible only at a very high temperature (=10 7 K) and a very high pressure.
3. For the same mass,the energy released in fusion process is much mote than that in the fussion process.
4. The fusionable substance is found in abundance.
