Q. No:11 Define relative density. Give the relative density of water.​

Answer 1

Answer:

Relative density is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material (i.e., water). It is usually measured at room temperature (20 Celcius degrees) and standard atmosphere (101.325kPa). It is unitless.

In SI units, the density of water is (approximately) 1000 kg/m3 or 1 g/cm3, which makes relative density calculations particularly convenient: the density of the object only needs to be divided by 1000 or 1, depending on the units.

Hope this helps you

Answer 2

Answer:

The relative density is the ratio of the mass of the substance in air at 20 °C to that of an equal volume of water at the same temperature
