Which of the following is NOT the characteristic of particles of the matter? 

The correct answer is They are very large in size..

Key Points

• Particles of matter are extremely small and are beyond the resolution of a standard microscope.
• They are in a state of continuous motion due to their kinetic energy, which varies with temperature.
• There is always space between particles of matter, which is evident from the diffusion of gases and mixing of liquids.
• Particles of matter attract each other with forces that vary depending on the type of matter.

Additional Information

• Brownian Motion:
  • It is the random movement of particles suspended in a fluid, resulting from their collision with quick atoms or molecules in the gas or liquid.
  • This phenomenon supports the theory that particles are in continuous motion.
• Diffusion:
  • It is the process by which particles spread from an area of high concentration to an area of low concentration.
  • Diffusion demonstrates that particles have space between them and are constantly moving.
• Intermolecular Forces:
  • These are forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions).
  • Examples include hydrogen bonds, Van der Waals forces, and ionic bonds.
• Kinetic Theory of Matter:
  • This theory states that matter is composed of a large number of small particles that are in constant motion.
  • The temperature of a substance is a measure of the average kinetic energy of its particles.
