Edexcel IGCSE Physics 7.24 Nuclear Fusion Questions

Describe fusion in a star as smaller nuclei joining to form a larger nucleus, with a loss of mass and release of energy from the reaction.

Exam points

Describe nuclear fusion as two smaller nuclei joining to create a larger nucleus.
Explain that fusion releases energy as mass is lost from the smaller nuclei; relate the mass-energy change to E = mc².

[Maximum number: 2]

Some of the energy stored in the nuclei of atoms can be used to generate electricity.

Nuclear fusion is another process that could be used to generate electricity.

Describe the process of nuclear fusion.

any two from:

MP1. creation of a (large) nucleus from small nuclei;

MP2. resulting in a loss of mass;

MP3. and the release of energy;

condone "fusing of two nuclei"

accept reference to $\mathrm{E}=\mathrm{mc}^{2}$ condone "converted to energy"
