Why does the chair in which you are currently sitting retain its same shape over time?
question options:
the particles of the chair are strongly held together.
the chair is lower in energy than the surrounding environment.
the particles of the chair are free to move and form their most stable positions.
the chair is made of particles that are relatively far apart and spread out to a maximum to form the chair shape.

Option (a) is the correct answer.

Explanation:

A chair is a solid substance and it is known that particles in a solid are closely held together by strong intermolecular forces of attraction.

Therefore, solids are rigid and have a definite shape.

Thus, we can conclude that the chair in which you are currently sitting retain its same shape over time because the particles of the chair are strongly held together.
