### Educational Explanation on Diffusion and Osmosis#### Scenario:2. **Observation:** A beaker of water and a beaker containing a sugar solution were placed in a closed container at room temperature. After some time, the volume of water in the beaker decreased, while the volume of the sugar solution increased. #### Explanation:This phenomenon can be explained through the principles of osmosis and vapor pressure.#### Diagram Analysis:The provided diagrams detail the initial and final states of the experiment:1. **Initial State:** - **Beaker 1**: Contains pure water. - **Beaker 2**: Contains a sugar solution. - Both beakers are placed under a closed dome/container.2. **Over Time:** - Water molecules from the beaker of pure water undergo evaporation. - Water vapor moves towards the sugar solution, which has lower vapor pressure due to the presence of sugar.3. **Final State:** - The volume of water in the beaker with pure water decreases as water moves out. - The volume of the sugar solution increases as it absorbs the water vapor.#### Underlying Principle:**Osmosis:** - Osmosis is the movement of water molecules across a semipermeable membrane from a region of lower solute concentration (higher water potential) to a region of higher solute concentration (lower water potential).- In this experiment, the movement is driven by the differences in vapor pressure rather than across a semipermeable membrane, but the principal idea of water moving from a region of higher concentration to lower concentration remains applicable.### Conclusion:The observed changes are due to the evaporation of water from the beaker of pure water, followed by the diffusion of water vapor and its subsequent absorption by the sugar solution, which has a lower vapor pressure compared to pure water. This drives the redistribution of water molecules, resulting in a decrease in water volume in one beaker and an increase in the other.---This explanation should help clarify the results of the experiment, illustrating the key concepts of diffusion and osmosis in a controlled environment.

What is a colligative property? O A property that depends on the number of particles in solution, but not on the nature of the particles. O A property that relates the temperature of a gas to the pressure of the gas. O A property that depends on the specific chemical behavior of the constituent elements and not on the amount in solution. O A property that can only be measured when the moles of gas are constant. O A property that enhances the solubility of a molecule in water.
