Characteristics of Matter Illustrated by the Observation
- Density: The observation that there is no increase in volume when 50 kg of sugar is dissolved in 100 ml of water illustrates the characteristic of density in matter. Density is a measure of how much mass is contained in a given volume. In this case, the sugar dissolves in the water without increasing the volume, indicating that the density of the resulting solution is higher than that of water alone.
- Particle Size: Another characteristic of matter that is illustrated by this observation is the particle size. When sugar is dissolved in water, the sugar molecules break down into smaller particles that mix uniformly with the water molecules. This results in a homogenous solution without any visible particles of sugar, showing that the particle size of the sugar has changed during the dissolving process.
- Solubility: The fact that the sugar dissolves in water to form a solution also demonstrates the characteristic of solubility. Solubility is the ability of a substance to dissolve in a solvent to form a homogeneous mixture. In this case, sugar is soluble in water, leading to the formation of a sugar-water solution without any separate layers or visible particles.
- Chemical Properties: The observation highlights the chemical properties of sugar and water. When sugar is dissolved in water, it undergoes a physical change where the sugar molecules are dispersed throughout the water molecules. This change is reversible, as the sugar can be recovered from the solution by evaporation of the water.
In conclusion, the observation of no increase in volume when sugar is dissolved in water illustrates several characteristics of matter, including density, particle size, solubility, and chemical properties.
