Finding the relative density of different objects

1.	Finding the relative density of different objects
Answer» e Density is the ratio of a density of a substance to the density of water at 4°C. So mathematically, RD = Density of a substance ÷ Density of water at 4 ° C RD= Mass of a substance ÷ Mass of same VOLUME of water at 4°C RD = Weight of a substance ÷ Weight of same volume of water at 4°C Using a RD Bottle, (M3 - M1) ÷ (M2 - M1). Where M1 is the mass of empty bottle, M2 is the mass of bottle + water, M3 is the mass of bottle with the required liquid Using Archimedes Principle (Weight of body in air) ÷ ( Weight of body in air - Weight of body in water) (Weight of body in air ÷ { Weight of body in air - Weight of body in liquid other than water}) × RD of that liquid The above two calculations of RD is done based on the principle of buoyancy , Archmides principle and Law of FLOATATION. It STATES that the loss of weight in a body when immersed in a liquid is equal to the weight of the liquid displaced by the body. Up thrust = Loss in weight = = Vol of liquid displaced× Density of liquid × ACCELARATION due to gravity = Mass of liquid displaced× Accelaration due to gravity = Weight of the liquid displaced
