  • How to Open a Tight Metal Lid on a Glass Bottle: Using Thermal Expansion
    The property of substance that can be used to open a tight metal lid from a glass bottle is thermal expansion.

    Here's how it works:

    * Heat the lid: Metal expands when heated. You can use hot water, a hairdryer, or even a lighter to gently heat the metal lid.

    * Expansion creates a gap: As the lid expands, it will become slightly larger than the opening of the jar. This small gap is enough to break the seal and make the lid easier to loosen.

    Important Note: Be careful not to overheat the lid, as this could cause the glass to crack or the lid to warp.
