Question

A substance in a specific state of matter was transferred from a cylindrical shaped container to a cube shaped container. The substance took different shapes in each container. Which of the following could be another characteristic of the substance. A. It is partially compressible B. It’s particles are arranged in a fixed pattern. C. It has very strong intermolecular forces between particles D. The particles move up and down without changing their position

Answer 1

Answer: Option (A) is the correct answer.

Step-by-step explanation:

In a solid substance, the atoms are held together by strong intermolecular forces of attraction. Hence, the atoms are not able t move freely but they are able to vibrate at their mean position.

As a result, solids have a definite shape and volume and also, they are incompressible in nature.

In liquids, the atoms are held together by less strong intermolecular forces of attraction as compared to solids. Therefore, atoms of a liquid are able to slide past each other. So, they are partially compressible in nature.

Also, liquids acquire the shape of container in which they are placed.

But in gases, the molecules are held together by weak intermolecular forces of attraction. Hence, atoms are able to move far away from each other as they have high kinetic energy.

Gases are highly compressible in nature.

Therefore, in the given situation as substance took different shapes in each container.

Thus, we can conclude that it is partially compressible could be another characteristic of the substance.

Answer 2

D. The particles move up and down without changing their position

Step-by-step explanation:

These are gases. They are typically known for their randomness and no fixed arrangement of their atoms.

Gases generally assume the volumes of the containers they fill. They spread easily and readily to fill the volume where they occupy. Also, gases are readily compressible as they lack intermolecular attraction between their molecules.
