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 inventor?Wally Minto
2. What is the structural design?Circular arrangement of sealed chambers connected in opposing pairs
3. What is the Minto wheel and how does it make power from heat?The Minto wheel is a special engine that uses a low‑boiling liquid like propane. When the liquid turns into gas, it pushes on the wheel’s chambers and makes the wheel spin.
4. Why does the Minto wheel need a hot side and a cold side?The hot side heats the fluid so it turns into gas, while the cold side cools it back into liquid. This hot‑and‑cold cycle keeps the wheel turning.

Thermodynamics: The branch of physics concerned with heat and its relation to other forms of energy and work.
Phase Transition: The physical process where a substance changes from one state (solid, liquid, gas) to another.
Working Fluid: The substance within a thermodynamic system that undergoes cyclic changes to produce work.
Temperature Gradient: A difference in temperature between two points or regions.
