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 scientific principle?Minimization of heat transfer (conduction, convection, radiation) through advanced insulation
2. What is the historical precursor?The haybox, a 19th and early 20th-century insulated cooking device
3. How does a thermal cooker keep food hot?The cooker has a special outer shell made of materials like vacuum layers, aerogel, or foam that stops heat from leaving by conduction, convection, and radiation.
4. Why is thermal cooking good for the environment?Because the cooker needs almost no extra heat, it uses less energy, which helps reduce greenhouse gases and saves money on electricity or gas.

Thermodynamics: The branch of physics dealing with heat and its relation to other forms of energy and work.
Thermal conductivity: A material's ability to conduct heat; low conductivity is desired for insulation.
Gelatinization: The process where starch granules absorb water and swell, thickening liquids, common in slow cooking.
