Does heat cause glass to expand?
When we heat up glass that has a high coefficient of thermal expansion, the glass expands. Since glass is brittle, the stress can cause it to crack (or shatter in the worst case). This is less likely to happen in Pyrex glass which does not expand as much in the first place.
Does cold water help open a jar?
Heat It Up
Fill a bowl with hot water, either from the tap or by heating on the stove. The heat will cause the metal lid to expand faster than the glass jar, making the seal easier to break. This method works especially well if the jar is cold to begin with.
