When a crystal of potassium permanganate is placed in a beaker containing water, its purple colour spreads throughout the water. What do you conclude from this observation about the nature of potassium permanganate and water? What is the first statement of the audio clip?

• When we place few crystals of potassium permanganate in a beaker containing water, we get two distinct layers-colourless water at the top and pink colour at the bottom.

• After few minutes, pink colour spreads and whole solution turns pink due to diffusion

• Since potassium permanganate is a solid substance, it does not possess so much space.

• Water molecules due to liquid state, collide with solid particles and intermix due to sufficient space between molecules.

Why do solids have a regular geometrical shape? What is the first statement of the audio clip?

• In solids, the particles have highly ordered arrangement

• t because the intermolecular forces between the particles are very strong.

• Therefore, solids have a regular geometrical shape.

Why are gases compressible but not liquids? What is the first statement of the audio clip?

• Gases are compressible because the intermolecular space is very large in gases,

• whereas liquids are not compressible because in liquids,

• the intermolecular space is less
