Characteristics of Particles of Matter

Out of solid, liquid or gas, which one has maximum inter-particle forces of attraction.

Out of solid, liquid or gas, which one has minimum spaces in between constituent particles?

Out of solid, liquid or gas, which one has the maximum movement of particles?

Even two or three crystals of potassium permanganate can impart colour to a very large volume of water. Which characteristic of particles of matter is illustrated by this observation?

When an incense stick (agarbatti) is lighted in one corner of a room, its fragrance spreads in the whole room quickly. Which characteristic of the particles of matter is illustrated by this observation?

Name the process by which a drop of ink spreads in a beaker of water. (Diffusion/ Attraction)

In which of the following the particles have the lowest forces of attraction?

When extremely small particles $\mathrm{X}$ derived from the anther of a flower were suspended in a liquid $\mathrm{Y}$ and observed through a microscope, it was found that the particles $\mathrm{X}$ were moving throughout the liquid $\mathrm{Y}$ in a very zig-zag way. It was also observed that the warmer the liquid $\mathrm{Y}$, the faster the particles $\mathrm{X}$ moved on its surface.

What does this experiment tell us about the nature of liquid $\mathrm{Y}$?

When extremely small particles $\mathrm{X}$ derived from the anther of a flower were suspended in a liquid $\mathrm{Y}$ and observed through a microscope, it was found that the particles $\mathrm{X}$ were moving throughout the liquid $\mathrm{Y}$ in a very zig-zag way. It was also observed that the warmer the liquid $\mathrm{Y}$, the faster the particles $\mathrm{X}$ moved on its surface. 

Name the scientist who discovered this phenomenon.

When extremely small particles X derived from the anther of a flower were suspended in a liquid Y and observed through a microscope, it was found that the particles X were moving throughout the liquid Y in a very zig-zag way. It was also observed that warmer the liquid Y, faster the particles X moved on its surface.

What causes the zig-zag movement of particles X?

When extremely small particles X derived from the anther of a flower were suspended in a liquid Y and observed through a microscope, it was found that the particles X were moving throughout the liquid Y in a very zig-zag way. It was also observed that the warmer the liquid Y, the faster the particles X moved on its surface.

What is the zig-zag movement of X known as ?

When extremely small particles X derived from the anther of a flower were suspended in a liquid Y and observed through a microscope, it was found that the particles X were moving throughout the liquid Y in a very zig-zag way. It was also observed that warmer the liquid Y, faster the particles X moved on its surface.

What do you think liquid Y is?

When extremely small particles X derived from the anther of a flower were suspended in a liquid Y and observed through a microscope, it was found that the particles X were moving throughout the liquid Y in a very zig-zag way. It was also observed that the warmer the liquid Y, the faster the particles X moved on its surface.

What could particles X be ?

What is Brownian motion? Draw a diagram to show the movement of a particle (like a pollen grain) during Brownian motion.

Ravi added a small amount of common salt to water taken in a graduated cylinder. On dissolution, there was no detectable change in the level of water. Explain why is it so?

Describe, what happens to the particles when sugar dissolve in water.

How will you demonstrate that particles of matter attract each other?

How will you demonstrate that particles of matter are continuously moving?

How will you demonstrate that particles of matter have spaces between them?
