Compare the diffusion rates of gases and liquids and explain how to draw a bar graph for experimental results.

From the comparison in question 1.1.6, the conclusion is that gases diffuse significantly faster than liquids. This is because gas particles are much further apart and possess higher kinetic energy, allowing them to move more freely and rapidly to fill the available space compared to liquid particles, which are closer together and have less kinetic energy.

To draw a bar graph, you would need the specific results recorded in your table. Since the table is not provided, I cannot draw the graph for you. However, here are the general requirements for drawing it:

• Caption: The graph needs a clear, descriptive title (e.g., "Effect of [Independent Variable] on [Dependent Variable]").
• Independent and Dependent Variables: The independent variable (the factor you changed, e.g., different substances or temperatures) should be plotted on the x-axis. The dependent variable (the factor you measured, e.g., rate of diffusion or time taken) should be plotted on the y-axis. Both axes must be clearly labeled with units.
• Neatness: Use a ruler to draw the axes and bars. Ensure the bars are of equal width and spaced evenly. Choose an appropriate scale for the y-axis to make the data clear.
