- Assertion (A) states that an iron ball floats on mercury but gets immersed in water. This is true. An object floats on a liquid if its density (or specific gravity) is less than the density (or specific gravity) of the liquid. The density of iron is approximately 7.8 g/cm³. The density of mercury is approximately 13.6 g/cm³. The density of water is approximately Reason (R) states that the specific gravity of iron is more than that of mercury. This is false. Specific gravity is the ratio of the density of a substance to the density of water. Specific gravity of iron is approx. 7.8. Specific gravity of mercury is approx. less than that of mercury (13.6).
Assertion (A): An iron ball floats on mercury but gets immersed in water. Reason (R): The specific gravity of iron is more than that of mercury.
