Answers to AQA GCSE Fusion reactions in stars (Physics)
Practice Questions
1.Name the process which allows for the formation of carbon in stars
Nuclear fusion
2. Write a nuclear fusion equation to explain how three helium-4 nuclei could fuse to form a carbon 12 nucleus.
3. Explain how very heavy elements such as uranium are formed by stars.
In stars with a mass greater than our Sun, fusion will occur to form elements heavier than iron. During the supernova stage of the life cycle of a massive star, the core is compressed so much that heavier elements such as uranium are formed.
