- Nuclear fusion increases the mass through fusing two nuclei together into one
- Nulear fusion releases a large amount of energy
- Nuclear fusion is a kind of process
- Therefore, nulcear fusion is a process that fuses two nuclei into one and releases large amount of energy

- Nulcear fusion is a process that fuses two nuclei into one and releases large amount of energy
- A process combines two nuclei into one and releases a large amount of energy
- So, the process is nulcear fusion

So, the process is nulcear fusion
Question: When two nuclei are combined into one nucleus, there is a slight change in mass and the release of a large amount of energy. What is this process called?
Context: - Nuclear fusion increases the mass through fusing two nuclei together into one 
- Nulear fusion releases a large amount of energy 
- Nuclear fusion is a kind of process 
- A process combines two nuclei into one and releases a large amount of energy
