\nAmong the given options, Acetone has the least density at room temperature.
\n<\/section>\n
\n– Approximate densities at room temperature:
\n – Milk: Approx. 1.03 g\/cm\u00b3 (slightly denser than water).
\n – Acetone: Approx. 0.79 g\/cm\u00b3 (a lightweight organic solvent).
\n – Red soil: Bulk density varies greatly but is typically in the range of 1.2 to 1.6 g\/cm\u00b3 or higher, depending on composition and compaction. Even the solid mineral components have densities around 2.6-2.7 g\/cm\u00b3.
\n – Iron: Approx. 7.87 g\/cm\u00b3 (a dense metal).
\n– Comparing these values, Acetone (0.79 g\/cm\u00b3) has the lowest density.
\n<\/section>\n
\n– Density is defined as mass per unit volume.
\n– Different substances have different densities due to the mass of their constituent particles and how closely they are packed.
\n– Solids are generally denser than liquids, which are generally denser than gases, though there are exceptions (e.g., ice is less dense than water).
