The heat causes the metal to expand making the lid slightly bigger so that it breaks contact with the jar.
That's what it does, how it does it I believe is this. Heat causes the atoms in the metal to move faster or to have more energy. The more energy something has, the more room each atom needs to function. That may be simplistic, but I think that is the idea.
Electrons can be removed easily from an atom because they are the outermost particles and have the least amount of attraction to the nucleus compared to protons and neutrons.

Yes they can be easily separated.
Aluminum sulfate is often added to water to help remove impurities, such as suspended particles, organic matter, and bacteria. It acts as a coagulant, bringing these particles together to form larger clumps that can be easily removed by filtration or settling.
Wind can most easily move small, lightweight particles such as dust, sand, and leaves. These particles are easily carried by the force of the moving air and are commonly observed being transported by wind.
A flocculent is typically made of polymers or inorganic compounds that help agglomerate and settle suspended particles in liquids. These chemicals work by neutralizing the charges on particles, allowing them to clump together and form larger flocs that can be easily removed through filtration or settling.
No, they have no strings. They have a slightly hard outer peel, but which is easily removed, and an inner pit, which is quite hard, but is also easily removed.
Particles in a suspension are larger than the particles of a solution, but they are not always so small that they cannot be easily seen with the eye.

The word "EASILY" is an adverb in this sentence. It modifies the verb "removed," indicating how the tarnish can be removed.
A liquid mixture in which particles can be seen and easily separated by settling or filtration is a suspension.
