Which of the following statements describes a solid? a.) it is easily compressed b.) its particles are packed together tightly c.) it takes the volume of its container d.) it takes the shape of its container

Option (B) is the correct answer.

Explanation:

In solids, molecules are held together by strong intermolecular forces of attraction. Hence, the molecules are much more closer to each other.

As a result, they are unable to move from their initial position and can only vibrate at their mean position.

Hence, a solid has definite shape and volume. Solids cannot be compressed.

Whereas in a liquid, particles are held by less strong intermolecular forces of attraction as compared to solids. Therefore, in a liquid molecules are able to slide past each other and thus, they can be slightly compressed.

Liquids do not have a fixed shape but they do have a fixed volume.

In gases, molecules are widely spread out as they are held by weak Vander waal forces. Hence, they do not have a fixed shape but they acquire the volume of container in which they are placed.

Thus, we can conclude that the statement its particles are packed together tightly, is correct.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
