Why you can heat up the lid of a jar to make it easier to open?
Heating the lid of a jar causes the metal to expand slightly, which can help loosen its grip on the jar.

This thermal expansion effect allows for a better seal break, facilitating the jar's opening.

Why do you use hot water to remove a tight metal cap easily?
Often, lids are made of metals which are great conductors of electromagnetic waves (including heat). When warm water is applied to a "difficult" lid, excitement of the atoms in the metal occurs (very slight) which causes a slight expansion. This expansion helps the lid to be moved from it's grip on the jar or bottle. This is also found in plastics. Although not through expansions. The heat from the warm water literally softens the plastic.
