Why those an egg float in salt water. Because I density of the egg is higher than that the density of tap water , so it sink density (a) as shown below in Equation 1, is the mass (m) ofa material per unit volume (v) , for example , the density of fresh water under standard conditions is approximately I gram ( g) per cubic centimeter (m3) .In other words, if you filled a 1-cm x1-cm x 1-cm box with freshwater , the water inside the box would have a mass of lighting salt to the water increases the density of the water increases the mass without changing the volume very...
