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 core engineering discipline?Combines thermodynamics, fluid dynamics, materials science, and safety engineering
2. What is the historical advancement?Shift from fire-tube to water-tube designs enabled higher pressures and efficiencies
3. What is a boiler and why does it make steam?A boiler is a machine that heats water until it turns into steam. The steam can warm homes or drive turbines to make electricity.
4. How do boilers stay safe when they get very hot and pressurized?Engineers use strong alloys that can handle high heat and pressure. They also add safety valves and design the structure to keep it from breaking.

Rankine Cycle: A thermodynamic cycle that converts heat into work, typically used in steam power plants.
Superheater: A component that increases the temperature of steam above its saturation point.
Water-tube Boiler: A boiler where water circulates inside tubes heated by external combustion gases.
