Final answer:
The student's question pertains to the process of dissolving sugar in water to form a solution, using the solute (sugar) and the solvent (water).
Step-by-step explanation:
The sentence 'Sugar .......... separately in one-fourth litre of water' is likely referring to the process of dissolving sugar in water to create a solution.
Let's consider an example to understand the concept better: Example 6.4.1, which involves dissolving 1.00 g of sucrose (C12H22O11) in 100.0 g of liquid water. In this case, the sugar, sucrose, is the solute, and the water is the solvent. When sugar is dissolved in water, it spreads out at the molecular level between the water molecules, occupying space and creating a homogeneous mixture known as a solution.
When comparing two solutions with equal volumes, such as two full water glasses, one with a single teaspoon of sugar and the other with one-quarter cup of sugar, the one with less sugar (the first cup) will contain more water. This is because the larger quantity of sugar in the second cup displaces more water than the teaspoon in the first cup.
To conduct an experiment with sugar and water, you might start by adding the appropriate mass of solute to a container, such as a test tube or a glass of water, and observe how the sugar dissolves when stirred or left to sit. When making observations, you might note how different amounts of sugar affect the dissolution process or the final volume of the solution in a given container.
