Which of the following examples shows that particles of matter have enough space between them?
Boiling of water
Potassium permanganate got evenly distributed in water
Breaking of iron nail
Lighting incense stick
Potassium permanganate got evenly distributed in water
When potassium permanganate (KMnO4тАЛ) crystals are added to water, they dissolve and the purple-colored particles spread uniformly throughout the water. This phenomenon demonstrates that matter is made of tiny particles and that there are vacant spaces between these particles, allowing the solute particles to occupy the interparticle spaces.
When potassium permanganate (KMnO4тАЛ) crystals are added to water, they dissolve and the purple-colored particles spread uniformly throughout the water. This phenomenon demonstrates that matter is made of tiny particles and that there are vacant spaces between these particles, allowing the solute particles to occupy the interparticle spaces.
Dissolving sugar or salt in a glass of water without significantly increasing the water level. The sugar particles slip into the empty spaces between the water molecules.
SPACES: Space Permits Atoms/molecules to Combine Evenly in Solutions.
Matter consists of extremely small particles with spaces between them. When a solid like potassium permanganate (KMnO4тАЛ) is dissolved in water, the individual particles of potassium permanganate separate and move into the intermolecular spaces present between the water molecules, resulting in a homogeneous purple solution.
Matter is composed of extremely small particles.
Particles of matter have spaces between them.
Dissolution of potassium permanganate in water demonstrates interparticle spacing and diffusion.
The uniform purple color shows even distribution of matter at the microscopic level.
Provides direct visual evidence of particulate nature of matter.
Demonstrates the process of diffusion in liquids.
Understanding solubility and solution chemistry.
Water purification and medication mixing.
Studying diffusion rates in different states of matter.
Option A (Boiling of water) demonstrates that particles of matter are continuously moving and change state upon absorbing thermal energy.
Option B (Potassium permanganate got evenly distributed in water) directly illustrates that particles have space between them.
Option C (Breaking of an iron nail) demonstrates interparticle attractive forces.
Option D (Lighting incense stick) demonstrates diffusion of gases and particulate motion.
B is correct тАФ Potassium permanganate got evenly distributed in water shows that particles of matter have enough space between them.
Always link experiments involving dissolving solids in liquids (like sugar or KMnO4) to 'intermolecular spaces', and diffusion or Brownian motion to 'continuous motion of particles'.
