physical properties can be used to compare and classify substances. a liquid is poured into a container with a solid powder. both substances are stirred until the solid is no longer visible to the human eye. which of the following physical properties of a solid is demonstrated by the process?

• solubility
• thermal conductivity
• melting point
• density

Explanation:

When a solid powder dissolves in a liquid and is no longer visible to the human - eye, it shows the property of solubility. Solubility is the ability of a substance (the solid in this case) to dissolve in a solvent (the liquid). Thermal conductivity refers to the ability to conduct heat, melting point is the temperature at which a solid turns into a liquid, and density is the mass per unit volume. None of these other properties are demonstrated by the solid disappearing in the liquid.

Answer:

solubility
