A stuck metal screw-top on a glass bottle can be opened by heating because metals generally have a higher coefficient of thermal expansion compared to glass. When heat is applied, such as by running the lid under hot water, the metal lid expands at a faster rate and to a greater extent than the glass container. This differential expansion creates a small gap between the lid and the bottle threads, effectively loosening the seal. Additionally, metals are better thermal conductors than glass, allowing the heat to distribute rapidly through the lid. While both materials expand when heated, the fact that the metal expands more than the glass is the primary physical principle used to overcome the friction or vacuum seal holding the lid in place.
