Why is it easier to loosen the metal lid on a glass jar after dipping it under a hot water?
The metal lid will expand much quicker than the glass jar that you’ve got, so that will expand and open up and then you can loosen it up. It also has a lower specific heat capacity so when it gets to a certain temperature that expansion happens quicker than the glass that it’s surrounded by.
Why do Jars get stuck?
Sometimes jar lids get stuck due to an extra strong seal from the factory. If there is enough room for the contents of the jar to shift, this will send it all to the lid and might break the seal.

Tap the lid of the jar on top a couple of times around the edge to pop the seal, then try to twist off the lid. You might need to repeat this a few times to get the lid to loosen.
Why did jammed metal lid open easily after warming?
The thermal conductivity of the metal top is much greater than that of the glass, and its specific heat is relatively low, so the temperature of the entire metal lid rises rapidly.
Does glass expand when frozen?
Non-tempered glass contains microscopic air bubbles that expand and contract as the glass is heated and cooled down, especially at extreme temperatures, like during canning and freezing. When those little air bubbles expand, they cause the glass to crack or even explode!.
