Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary classification?Fire-tube (lower pressure, heating) vs. Water-tube (higher pressure, power generation)
2. What is the modern relevance?Essential for electricity generation, industrial processes, and building climate control
3. Why do boilers make steam instead of just hot water?When the water gets very hot, it turns into steam, which can push on turbines to make electricity. Steam can also be used for heating and many factories.
4. How do boilers stay safe when they work at high pressure?Modern boilers are built with strong metal and have safety controls that keep the pressure and temperature at safe levels. They also use special designs like water‑tube boilers that are safer than older fire‑tube ones.

Thermodynamics: The branch of physics dealing with heat and its relation to other forms of energy and work.
Phase Change: The physical process where a substance changes from one state (solid, liquid, gas) to another.
Superheated Steam: Steam heated beyond its saturation temperature at a given pressure.
