How Do You Measure Density SI unit of density is kg/m3 and CGS unit of density is g /cm3 1 gm/cm3 = 1000 kg/m3 Different substances have different densities which gets affected by temperature. Respective density of a substance decreases on heating due to the expansion of the substance. Water has anomalous expansion. When water is cooled at 4ºC, its volume … [Read more...] about How Do You Measure Density
