What are the aims of experiments on osmosis and diffusion?

The aims of experiments on osmosis and diffusion are to:

1. Understand the processes of osmosis and diffusion and how they affect the movement of molecules across a semi-permeable membrane.
2. Investigate the factors that affect the rate of osmosis and diffusion, such as concentration gradients, temperature, and surface area.
3. Determine the direction of movement of molecules in different solutions and predict the outcomes of osmosis and diffusion experiments.
4. Explore the role of osmosis and diffusion in biological systems, such as the movement of water and nutrients in cells and tissues.
5. Develop practical skills in conducting experiments, collecting data, and analyzing results to draw conclusions about osmosis and diffusion.

Aims of Experiments on Osmosis

- To demonstrate the process of osmosis.
- To investigate the factors affecting osmosis, such as:
- Concentration gradient
- Temperature
- Membrane permeability
- To determine the osmotic pressure of a solution.

Aims of Experiments on Diffusion

- To demonstrate the process of diffusion.
- To investigate the factors affecting diffusion, such as:
- Concentration gradient
- Temperature
- Size and shape of molecules
- To determine the diffusion coefficient of a substance.
- To apply the principles of diffusion to real-world situations, such as gas exchange and nutrient transport.
