Why can you loosen a metal lid by holding it under hot water?
Metals expand when heated due to an increase in the average distance between atoms. When a metal lid is held under hot water, the lid expands slightly, increasing its circumference. As the lid becomes looser, it becomes easier to remove. This phenomenon is known as thermal expansion.
