"Nuclear Energy" Energy and Sustainable Development PPT Teaching Courseware

Part One Content: A Classification Practice of Knowledge Key Points

Knowledge point 1: Understand nuclear energy

1. Protons and neutrons are tightly bound together by the powerful ________, so the atomic nucleus is very strong. However, once the atomic nucleus is ________ or ________, it is possible to release amazing energy, which is nuclear energy.

2. The particles that make up the nucleus are ()

A. Positively charged protons and negatively charged electrons

B． Positively charged protons and uncharged neutrons

C． Positively charged protons, negatively charged electrons and uncharged neutrons

D. Negatively charged electrons and uncharged neutrons

Knowledge point 2 Nuclear fission and nuclear fusion

3. At the end of 1938, scientists used ________ to bombard a relatively large ________ for the first time, causing it to ________. Humanity effectively obtained a large amount of nuclear energy. This reaction is called nuclear fission.

4. Nuclear fusion refers to the way in which atomic nuclei with very high mass are combined into new __________ under ________ to obtain nuclear energy.

5. Observe Figure 22-2-1 and answer the following questions.

(1) What simulates nuclear fusion in Figures A and B is ________.

(2) Briefly summarize the two laws of nuclear fission:

①The uranium nucleus is bombarded by neutrons and splits into two parts;

② One neutron produces more neutrons after bombarding the uranium nucleus.

(3) Briefly explain the prospects of nuclear fusion: Deuterons are abundant in seawater. Humans can utilize nuclear energy by controlling fusion, which is expected to completely solve the energy problem.

6. Which of the following statements is correct ()

A. Nuclear energy, like oil, is a conventional energy source

B． Nuclear power plants use nuclear energy released by nuclear fission to generate electricity

C． Nuclear power plants use nuclear energy released by nuclear fusion to generate electricity

D. The chain reactions that occur when nuclear power plants generate electricity and atomic bombs explode are both uncontrolled

Nuclear energy PPT, part 2 content: Comprehensive practice of B law method

8. Which of the following statements about nuclear energy development do you think is correct ()

A. Stop developing nuclear energy, because developing nuclear energy will bring terrible nuclear leaks and cause far more harm than good.

B． Nuclear energy is a stable, efficient and clean secondary energy

C． Nuclear power plants develop nuclear energy by utilizing the nuclear energy released during controlled nuclear fission.

D. Nuclear energy development is absolutely safe, and even if there is a nuclear leak, it is clean and pollution-free.

9. Figure 22-2-3 shows the Hongyanhe Nuclear Power Station, the first nuclear power plant in Northeast my country. What occurs in the nuclear reactor of the nuclear power plant is the ________ (optional "fusion" or "fission") reaction of the atomic nucleus; the nuclear power plant ultimately converts nuclear energy into It is ______ energy, and nuclear energy is a ______ (optional "first" or "second") secondary energy source

Nuclear energy PPT, the third part: practical practice of C high-frequency examination questions

10．2018·Liaocheng Among atoms, nuclei, electrons, neutrons, and protons, the negatively charged ones are __________. A nuclear reactor is a device that releases nuclear energy through a controlled ________ (optional "fission" or "fusion") reaction.

11.2018· As a new energy source, Xiaogan nuclear energy is gradually being developed and utilized by people. Nuclear power plants use nuclear energy to generate electricity. Nuclear fuel is used in the reactor through ________ (optional "fission" or "fusion") to convert nuclear energy into It is converted into electrical energy and transmitted to the national grid for use by thousands of households; the voltage of my country's household lighting circuits is ________V.
