Test 10 Review: Nuclear and Gases AAC 2022

A nuclear fission reaction occurs when a uranium-235  atom is bombarded with a neutron. This reaction is used to produce energy in a nuclear power plant. Why is it not possible to carry out a nuclear fusion reaction in a nuclear reactor?

• A fusion reaction releases harmful rays
• A fusion reaction is difficult to control
• A fusion reaction requires extremely low temperature and pressure
• A fusion reaction requires extremely high temperature and pressure

Which of the following statements BEST describes nuclear fission?

• Nuclear fission inside stars can absorb or release energy
• Nuclear fission causes the reaction inside an atomic bomb
• Nuclear fission is usually present in endothermic reactions
• Nuclear fission cannot be used to produce power in nuclear energy plants

Which of the following statements BEST describes nuclear fusion?

• Nuclear fusion is a common source of energy
• Nuclear fusion usually requires freezing temperatures
• Nuclear fusion usually requires a high-temperature environment
• Nuclear fusion releases a small amount of energy compared to most chemical reactions
