Matter and its Characteristics

Matter is anything that has mass and occupies space. It can exist in different states such as solid, liquid, or gas. Matter is composed of tiny particles called atoms, which are further made up of subatomic particles like protons, neutrons, and electrons. Let's discuss the characteristics of matter and explain why option B is not a characteristic of matter.

Characteristics of Matter:

1. Matter is made up of extremely small particles: Matter is composed of atoms and molecules, which are the smallest units of matter. These particles are so small that they cannot be seen with the naked eye.

2. The particles of matter are continuously moving: The particles of matter are in a constant state of motion. This movement can be in the form of vibration, rotation, or translation, depending on the state of matter. For example, in solids, particles vibrate in fixed positions, while in liquids and gases, particles move more freely.

3. The particles of matter attract each other: There are attractive forces between the particles of matter. These forces hold the particles together and are responsible for the cohesive properties of matter. For example, the force of attraction between water molecules gives rise to surface tension.

4. There is no space between particles of matter: This statement is not a characteristic of matter. In reality, there is space between particles of matter. The concept of intermolecular space is crucial in understanding the behavior and properties of matter. The arrangement and amount of space between particles determine the density and compressibility of matter.

Explanation of Option B:

Option B states that there is no space between particles of matter, which is not true. In reality, there is space between particles, even in solids. The particles in a solid are arranged in a regular pattern, but there are still gaps or interstices between them. Similarly, in liquids and gases, the particles are not tightly packed, and there is space between them.

The presence of intermolecular spaces allows matter to undergo various physical and chemical changes. For example, it enables the expansion of substances on heating, the diffusion of gases, and the movement of liquids in capillary tubes.

Therefore, option B is not a characteristic of matter as there is indeed space between particles of matter.

B, there is no space between particles of matter
