Question

An iron block _____________________ in water . (sinks/floats)

Answer 1

1. Density can be defined as mass per unit volume.
2. The SI unit of density is kg/m³ while the CGS unit is g/cm³.
3. An object floats a liquid when the weight of the object balances the upward push of the liquid or if the object is less dense than the liquid it is immersed in.
4. An object sinks in a liquid when the weight of the object is more than the upward push of water or if the object is denser than the liquid, it is immersed in.
5. The iron-block sinks in water because Iron has more density than water.

Hence, An iron block sinks in water.
