The physical properties of matter produce many cause and effect relationships. which effort is produced by the close packing of molecules in a solid?
a. decreased compressibility
b. increased compressibility
c. increased motion of molecules
d. increased kinetic energy

A.

Explanation:

We know quite well that there are three states of matter. Solid,liquid and gaseous states.

While the gaseous states gives the highest freedom of movement, the solid state gives the least freedom of movement. Molecules and atoms of a solid are so tightly packed.

This makes them very dense as they are held together by strong intermolecular forces of attraction. These strong forces prevents the movement of the particles.

As these particles are strongly attracted towards each other, they tend to be incompressible.

since electrons are negative the answer is neagtaive

c) should be the answer.
