Nuclear energy can be controlled to provide us with power. In a nuclear power plant, control rods are lowered into the reactor to keep the reaction in check. But the uranium still gets very hot, and so a coolant, a liquid or a gas, moves through the reactor. When the hot coolant leaves the reactor, it goes to a boiler to make steam. It is this steam that powers generators to make electricity for our homes and factories.
Water turns to steam when it is heated to the boiling point.
A group of things or parts working together or connected in some way so as to form a whole. The pressure of steam, water, or air against the vanes causes the shaft to turn. This metal is one of the heaviest of all known elements. It was named after the planet Uranus. Uranium gives off radioactivity.
