Explain why gases diffuse faster than liquids and how to represent diffusion experiment results in a bar graph.

1.1.8 To draw a bar graph for the results of the diffusion experiment (food coloring in water at different temperatures):

• The independent variable (temperature of water: hot, room temperature, ice) should be on the X-axis.
• The dependent variable (rate of diffusion or time taken for diffusion/spreading) should be on the Y-axis.
• The graph should have a clear caption (e.g., "Effect of Temperature on the Rate of Diffusion of Food Coloring in Water").
• Each bar should represent the diffusion rate/time for a specific temperature, and the graph should be drawn neatly with appropriate scales.
