Solution
Nuclear fusion: In nuclear fusion, lighter nuclei fuse to form heavier nuclei.
Explanation: The fusion of nuclei is a difficult process as all nuclei are positively charged and repel each other. So, to overcome mutual repulsion, they must have sufficient kinetic energy. Hence, to give them sufficient kinetic energy, they must be heated at a very high temperature.
Hence, Nuclear fusion is carried out at high temperatures.
