प्रश्न
The volume of 50 g of a substance is 20 cm3. If the density of water is 1 g cm−3, will the substance float or sink?
उत्तर
The volume of the substance = 20 cm3
Mass of the substance = 50 g
Since density = `"mass"/"volume"`
∴ Density = `(50 g)/(20 cm^3) `
= 2.5 g/cm-3
Therefore, the density of the given substance = 2.5 g/cm-3
The substance will sink in water because the density of the substance is greater than the density of water, i.e. 1 gcm−3.
