Which process is carried out at high temperature: Nuclear fusion or Nuclear fission?
The concept used: Nuclear Energy
Step 1: Nuclear Fusion:
The process of fusing two low mass number atoms into a single atom is known as nuclear fusion. In the process of fusion of two elements, a large amount of energy is released that increases the temperature of the process by about 100 million Kelvin.
Step 2: Nuclear Fission:
When a high mass number element is split into two parts, then this splitting process is known as nuclear fission. In the process of fission, the energy is released when an element is broken down into two parts, but the amount of energy released is less than the energy required for the fusion process. Therefore, the rise in temperature in the fission process is less than in the fusion process.
Thus, nuclear fusion takes place at high temperatures.
