Question

which of the following physical properties of sugar is demonstrated by the process?

melting point
density
thermal conductivity
solubility

Explanation:

The process shows sugar being dissolved in water to form a sugar solution. Solubility is the ability of a substance (sugar) to dissolve in a solvent (water). Thermal conductivity refers to the ability to conduct heat, density is mass per unit volume, and melting point is the temperature at which a solid turns to liquid. None of these other properties are demonstrated in the dissolution process.

Answer:

solubility
