The zig-zag movement of particles suspended in liquids and gas is called …….. motion , named after the scientist ………

Q. 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.
(a) What could particles X be ?
(b) What do you think liquid Y is ?
(c) What is the zig-zag movement of X known as ?
(d) What is causing the zig-zag movement of particles X ?
(e) Name the scientist who discovered this phenomenon.
(f) What does this experiment tell us about the nature of liquid Y?
