Question

How would you define 'density' ?

Answer 1

Density =mass/ volume It is the mass per unit volume. For e.g- The mass of a body is 200 kg. And the volume is 100 cubic metre. Then the density =?? Answer- Mass =200 kg Volume = 100 cubic metre Therefore, Density = mass/volume = 200 kg /100 cubic metre = 2 kg/cubic metre (ans.) **Note :: The S.I unit of density is kg/ cubic metre Hope this helps you

Answer 2

Density -

✴Density of a substance is defined as the mass of the substance per unit of volume .

✴Density = Mass/Volume

✴SI unit of Density = kg/m^3

✴CGS unit of Density = g/cm^3

✴Density is the characteristic property of a substance.

✴The density of substance determines how densely the matter is packed in a certain volume of that substance.

✴D = mN . Where m = mass of one molecule , N = Number of molecules per unit volume
