Question

A copper piece of mass 100g when immersed in water contained in a measuring cylinder raises the level of water from 20 ml to 40 ml . Find volume of a piece of copper . And the density of copper

Answer 1

Answer:

5 g/cm^3 or 5000 kg/m^3

Explanation:

As water level increased by 20 ml, we can say that the volume of copper piece is 20 cm^3, according to Archimedes principle.

Density = mass/volume

= 100g/20cm^3

= 5 g/cm^3

= 5000 kg/m^3
