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 common heating element material?Nichrome (nickel-chromium alloy) due to its high resistivity and thermal stability
2. What is the key industrial applications?Metal smelting, glass manufacturing, ceramic firing, and material drying processes
3. What is electric heating and how does it work?Electric heating turns electricity into heat by passing current through a conductor that resists the flow. The resistance makes the conductor warm up, a process called Joule heating.
4. Why do electric heaters use materials like nichrome?Nichrome is a special alloy that resists electricity and can stay hot without rusting. This makes it a good, long‑lasting heating element for things like toasters and ovens.

Joule Heating: The dissipation of electrical energy as heat due to resistance in a conductor.
Nichrome: An alloy of nickel and chromium used for heating elements due to its resistance and durability.
Heat Pump: A device that transfers thermal energy from a colder to a hotter location using mechanical work.
Coefficient of Performance (COP): A measure of a heat pump's efficiency, representing the ratio of heating output to energy input.
