Question

serena is mixing a material into a beaker filled with a liquid. she notices that the material seems to disappear into the liquid. what physical property of the material is serena most likely observing?
solubility
conductivity
magnetism
density

Explanation:

Solubility is the ability of a substance (solute) to dissolve in a liquid (solvent). When Serena mixes a material into a liquid and it seems to disappear, it indicates that the material is dissolving in the liquid, which is related to solubility. Conductivity is about the ability to conduct electricity or heat. Magnetism is related to being attracted or repelled by a magnet. Density is the mass per unit volume. Since the key observation is the material disappearing (dissolving) in the liquid, solubility is the relevant property.

Answer:

solubility
