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 ?

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?

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 causes the zig-zag movement of particles X?

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 $\mathrm{X}$ 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 $\mathrm{Y}$?

What is the common unit of temperature?

What is the normal room temperature?
