4. the figure above is a model of atoms in a sample at room temperature. which physical property does this sample have? a. it can be poured
b. it can expand to fill its container
c. it cannot be compressed
d. it has a low boiling point

Option (C) is the correct answer.

Explanation:

It is known that in a solid, molecules are held together by strong intermolecular forces of attraction. As a result, they are unable to move from their initial place but they can vibrate at their mean position.  

Hence, in solid substances the molecules have low kinetic energy.

On the other hand in liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.

In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.

Thus, we can conclude that given figure shows a physical property that it cannot be compressed.

answer: a) a compound microscope has a greater magnification ability than a simple microscope.
