## How to measure Density of a substances

Hi viewers: Today we will discuss about another physical quantity and that is density of a substances and how to measure the density of a substance.  This physical quantity takes derived units, which we will discuss in the following  DENSITY What is density? The density of a substance (solid, liquid and gas) is defined as mass per unit volume at a particular temperature. OR in other words we can say The quantity of matter contained in a given volume of a substance at a particular temperature is called its density   Density = Mass / Volume Eg.  Density of water   In CGS system, Density of water is 1 gm/cc at 4 °C In FPS system, Density of water is 62.5 pound/cft In MKS system, Density of water is 1000 kg/cubic metre   Units of density In CGS system, it is gm/cc In FPS system, it is pound/cft In MKS system, it is kg/cubic metre   Experiment 1  (Note:  All experiments should be written in passive voice and past tense) Objective:  To measure the density of an irregular solid that does...
