Question

explain why the metal lid of a bottle or jar unscrews more easily after holding it in a boiling water for a few minutes ​

Answer 1

lets take an glass jar for example

Step-by-step explanation:

The metal lid and the glass jar absorb different amounts of thermal energy and therefore expand at different rates. Metals, being good conductors of heat, are able to absorb thermal energy from the hot water more easily. Glass, on the other hand, being a bad conductor of heat, cannot absorb the heat energy as well
