Harnessing the Energy of Atoms with Nuclear Power

Nuclear power is energy from atoms, primarily using uranium due to its large size and weak atomic force. The process involves fission, where uranium atoms are split by neutrons, releasing energy. This energy heats water to spin turbines, generating electricity. Nuclear power plants control this chain reaction with control rods.

What is the strongest force in nature that holds the nucleus together?

• Frictional force

• Nuclear force

• Gravitational force

• Electromagnetic force

Why is uranium particularly suitable for the fission process?

• It is abundant in the Earth's crust

• It has a small atomic size

• Its atomic force is relatively weak

• It is non-radioactive

How does the energy content of uranium compare to coal?

• Uranium has the same energy as coal

• Uranium has more energy than coal

• Uranium is not used for energy

• Uranium has less energy than coal

What role do control rods play in a nuclear reactor?

• They generate electricity directly

• They cool down the reactor

• They absorb neutrons to control the reaction

• They speed up the chain reaction

What is the primary function of the turbines in a nuclear power plant?

• To heat the water

• To absorb excess neutrons

• To split uranium atoms

• To convert steam into electricity
