Density · घनत्व
Density = mass ÷ volume. Units: g/cm³ or kg/m³ (1 g/cm³ = 1000 kg/m³). Water: 1 g/cm³.
Things less dense than water float (ice 0.92, cork, most wood); denser things sink (iron 7.87, glass, aluminium 2.70).
For Class 8 and 9 (NCERT Curiosity 8, “The Amazing World of Solutes, Solvents, and Solutions”). Densities are standard values; numeric answers computed by a program.
