Question

A substance in a specific state of matter has a definite volume but it does not have a rigid structure. Which of following could be another characteristic of the substance? It is highly compressible. It also has a definite shape. Its particles move randomly at high speeds. Its intermolecular forces can be partially overcome.

Answer 1

The Asnwer is D. Intermolecular forces can be partially overcome

Step-by-step explanation:

I took the test and got it right.

Answer 2

Answer: Its intermolecular forces can be partially overcome.

Explanation:

Solid state : In this state, the molecules are arranged in regular and repeating pattern. They have fixed shape and fixed volume. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another. They are in compressible.

For example : Copper

Liquid state : In this state, the molecules are present in random and irregular pattern. They have fixed volume but take the shape of the container. The molecules are closely packed but they can move from one place to another and thus intermolecular forces can be overcome. They are less compressible.

For example : water

Gaseous state : In this state, the molecules are present in irregular pattern. They have neither fixed shape nor volume.The molecules are not closely packed and they can move randomly at high speeds. They are highly compressible.

For example : Helium gas
