The products of nuclear fission includes _______

• neutrons and electrons
• two atoms and some neutrons
• two atoms and some electrons
• two atoms and some protons

What is a chain reaction?

• When electrons are emitted causing electricity
• When a nuclear fission reaction occurs, the protons emitted can strike other nuclei in the sample, and cause them to split
• When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, and cause them to split
• When a nuclear fission reaction occurs, the electrons emitted can strike other nuclei in the sample, and cause them to split

What do neutron moderators or control rods do in a nuclear reactor?

• Regulate the rate of reaction  by absorbing and slowing neutrons
• Produce electricity
• Produce neutrons to increase the rate of reaction
• Reduce heat produced by the uranium rods

How is the heat generated by the reactor core of a nuclear power plant used to provide power to buildings?

• It is used directly to heat homes and offices
• It generates steam, which turns a turbine, powering a generator
• It generates steam, which is then condensed back to water. This process produces energy
• All of the above

Nuclear power uses ____ for fuel.

• steel
• coal
• uranium
• hydrogen

Nuclear energy uses _____ to turn turbines to power a generator.

• wind
• water
• steam
• solar
