Question

written Experiment to measure Density of solid on practical pages.​

Answer 1

Answer:

1. Density: The density of a substance is defined as the mass per unit volume,[D= MV]
2. Here, D = Density of the body, M = Mass of the body, V = Volume of the body.
3. S.I. unit of density = Kgm-3 or Kg/m-3, c.g.s. unit of density = g/cm-3 or g cm-3.
4. Floating bodies: The density of water is 1 g/cm3 (c.g.s. system) and 1000 kg/m3 (S.I. system).
5. Case (a) If the density of a body is more than 1 g/cm3 or 1000 kg/m3 then the body will sink in water.
6. Case (b) If the density of a body is less than 1 g/cm3 or 1000 kg/m3 then the body will float on water.
7. Case (c) If the density of a body is same i.e. 1 g/cm3 or 1000 kg/m3 then the body will half float and half submerge in water.

Answer 2

Answer:Tie a metal bob (or any solid) with the string of cotton to the hook of the spring balance. ...

Hold the spring balance (or tie it to the stand), suspended with the metal bob in air. ...

Pour the water in the measuring cylinder and record the initial volume of water, let it be ' V1'
