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 key design parameters?Surface area, fluid flow rates, material thermal conductivity, and temperature differentials
2. What is the technological impact?Essential for energy efficiency, process optimization, and thermal management in diverse industries
3. How does a heat exchanger keep cars from overheating?In a car, the radiator is a type of heat exchanger that takes hot engine fluid and releases its heat into the air, preventing the engine from getting too hot.
4. Why are heat exchangers good for the planet?By moving waste heat instead of letting it escape, heat exchangers reduce energy waste and help lower greenhouse gas emissions.

Thermal Energy Transfer: The movement of heat from a region of higher temperature to a region of lower temperature.
Convection: Heat transfer through the movement of fluids (liquids or gases).
Conduction: Heat transfer through direct contact of particles within a substance or between substances.
