Physical quantities and measurements , Physics : CBSE and ICSE BOARD .
Its very helpful to all kind of competitive exam .
Topic :- Physical quantities and Measurement.
Key concepts
1) Measurement of density of irregular solids using a Eureka can.
2) Measurement of density of irregular solid using a measuring cylinder.
3) Measurement of density of liquids.
4) Relative density.
5) Floating and sinking.
6) Variation of density with temperature.
7) Comparison of densities in three States of matter.
DENSITY
Definition :-
Density is defined as the mass per unit volume of a substance.
i.e , Density ( d ) = mass (m) / volume (v)
Or, d = m / v
Unit :-
CGS :- g/cm^3
SI :- kg/m^3
