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 paricles 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 discoverd this phenomenon. (f) What does this experiment tell us about the nature of luquid Y? |
