Question

Which of the following is not a state of matter?

Answer 1

Answer: Option (C) is the correct answer.

Explanation:

Solid and liquid are the states of matter. Plasma is also a state of matter where a number of electrons move freely around the nucleus of an atom.

Whereas water is a liquid itself and liquid is a state of matter but water is not a state of matter.

Therefore, we can conclude that water is not a state of matter.

Answer 2

$\boxed{{\text{C}}{\text{. Water}}}$  is not a state of matter.

Further Explanation:

Matter:

Anything that acquires space and has mass is termed as matter. It is made up of atoms. These atoms can be bonded so strongly or can be far apart from each other. The states of matter can be classified on the basis of features that are visible or can be felt.

States of matter:

1. Solid

It has a definite shape and volume. These are generally hard and have a regular arrangement of its constituent particles. These can be amorphous or crystalline. The intermolecular forces in the solids are very strong and thus the motion of particles in solid is almost negligible. Rock, wood, sugar, and diamond are examples of solids.

2. Liquid

It has a definite volume but can have the shape of any container in which it is placed. The intermolecular forces in the liquids are weaker than that in solids and thus the motion of particles in liquids is more as compared to solids. These have the property to flow. Water, mercury and bromine are examples of liquids.

3. Gas

It has neither a definite shape nor a definite volume. These are highly compressible and have an irregular or disordered arrangement of its constituent particles. The intermolecular forces in the gases are the weakest and thus the motion of particles in a gas is very high. Oxygen, hydrogen and carbon dioxide are examples of gases.

4. Plasma

It has neither a definite volume nor a definite volume. It is present in ionized gases but its uniqueness differentiates it from gases. Plasma contains free charges that make it conductive. Stars and neon signs are examples of plasma.

So solid, liquid and plasma are the states of matter. But water is an example of liquid and therefore an example of a state of matter. Therefore water is not a state of matter.
