so what was your results?

To investigate the effects of molecular forces on the surface shape of a meniscus or droplet, you would typically conduct an experiment involving these substances: water, oil, glycerine, nail polish remover, and methylated spirit. The main objective would be to observe how each substance behaves and forms a meniscus or droplet on a surface.

Here's a step-by-step guide on how to conduct this investigation:

1. Set up a clean and dry surface, such as a glass or plastic surface, where you can place droplets of the substances.

2. Start by placing a small droplet of water on the surface. Observe the shape of the meniscus formed by the water droplet. Take note of whether it forms a concave or convex shape.

3. Repeat the process for the remaining substances: oil, glycerine, nail polish remover, and methylated spirit. Place a small droplet of each substance and observe the shape of the meniscus formed.

4. Compare the shape of the meniscus formed by each substance. Note any similarities or differences.

5. Analyze the results and consider the molecular forces at play. For example, water typically forms a concave meniscus due to the cohesive forces between water molecules being stronger than those between the water and the surface. Oil, on the other hand, tends to form a convex meniscus due to weaker cohesive forces.

6. Consider the nature of the substances themselves. Glycerine, nail polish remover, and methylated spirit may exhibit different effects on the surface shape based on their chemical properties and strength of intermolecular forces.

7. Summarize your findings and draw conclusions regarding the effects of molecular forces on the surface shape of the meniscus or droplet for each substance.

It is important to note that variations in the experimental setup and conditions can affect the outcome of the investigation. Additionally, using specialized equipment, such as a goniometer or contact angle measurement tools, may provide more precise and quantitative data on the surface shape of the meniscus.
