Gittel's town gets its electricity from a nuclear power plant, and her textbook says the sun runs on nuclear energy too. Same word, two machines. Which process runs where?
You can tell fission from fusion, and a controlled chain reaction from an uncontrolled one. This lesson matches each process to the thing it runs.
A nuclear power station runs on a controlled fission chain reaction.
An uncontrolled chain reaction is what a fission weapon deliberately creates.
Fusion powers the sun and the stars.
Fusion power stations are still experimental.
A nuclear power plant runs on controlled fission, not fusion.
Cosimo sees the cooling tower of the town's nuclear power plant and asks what kind of nuclear reaction runs inside. What is the answer?
A nuclear power station runs on a controlled fission chain reaction.
Controlled means on average exactly one neutron from each fission goes on.
A controlled fission chain reaction runs inside the plant: not fusion, and not an uncontrolled chain.
A space documentary says the sun will shine for billions of years more. Which nuclear process is it relying on?
Fusion powers the sun and the stars.
In the sun's core, hydrogen nuclei fuse into helium and release energy.
The sun relies on fusion.
Which nuclear process runs in a nuclear power station's reactor?
Which nuclear process keeps the sun and the other stars shining?
Cosimo says: 'Fusion power stations are still experimental.' Is Cosimo correct?
What does a fission weapon deliberately create?
Which of these runs on controlled fission?
Which statement correctly matches a nuclear process to its application?
