material in which thermal energy doesn’t move
easily
![Page 4: Heat Vocabulary. INSULATOR material in which thermal energy doesnt move easily.](https://reader036.fdocuments.us/reader036/viewer/2022062504/5a4d1b907f8b9ab0599c0e20/html5/thumbnails/4.jpg)
Examples: A glove used to take
something out of the oven. Heat
doesn’t transfer so you don’t get burnt
