What are the characteristics of the particles of matter?A Particles of...
The characteristics of particles of matter are as follows:
1. Particles of matter have space between them
When we dissolve salt in water, it is observed that the particles of salt get evenly distributed in water. Also, it is observed that the presence of salt particles did not change the level of water in the beaker. This could be possible only if the particles of salt were accommodated in between the water particles. Thus, this clearly proves that space exists between water particles.
2. Particles of matter are in continuous motion
We know that there is a lot of space present between the particles of matter. Particles of matter are never at rest and keep moving continuously in these free spaces. The particles of matter move continuously and their speed increases with an increase in temperature.
3. Particles of matter attract each other
The particles of matter attract each other. However, this force of attraction varies from matter to matter.

Particles of matter are the building blocks of everything around us. They can be found in various forms such as atoms, molecules, and ions. These particles possess certain characteristics that define their behavior and interactions with each other. Let us explore these characteristics in detail:
Continuous Motion:
Particles of matter are in continuous motion. This motion can be in the form of vibration, rotation, or translation. For example, the particles in a gas move freely and rapidly, constantly colliding with each other and the walls of the container. In a solid, the particles vibrate about fixed positions, while in a liquid, they have more freedom to move and can slide past each other.
No Spaces Between Particles:
Contrary to option (b), particles of matter do have spaces between them. The amount of space between particles depends on the state of matter. In a solid, the particles are closely packed and have limited space between them. In liquids and gases, the particles have more space between them, allowing them to move more freely. This is evident from the fact that substances can be compressed, which indicates the presence of spaces between particles.
Attraction between Particles:
Particles of matter do attract each other. This is due to intermolecular forces, such as van der Waals forces, hydrogen bonding, and electrostatic interactions. These attractive forces play a crucial role in determining the physical properties of substances, such as boiling point, melting point, and viscosity. The strength of these forces varies depending on the type of particles and the conditions they are in.
Size of Particles:
Particles of matter are extremely small in size. Atoms, which are the fundamental particles of matter, have sizes on the order of nanometers (10^-9 meters). Molecules and ions are composed of multiple atoms and can be larger in size, but they are still microscopic compared to everyday objects. The small size of particles allows them to interact and move in unique ways, giving rise to the diverse properties of matter.
Conclusion:
In conclusion, the characteristics of particles of matter include continuous motion, spaces between particles, attraction between particles, and small size. These properties are fundamental to understanding the behavior and properties of matter in its various states. Option (b) is the correct answer as it correctly identifies the characteristics of particles of matter.
