Density is an important property of a material and is used as a quality standard in our daily life and many industries.Definition of density:Density is defined as the mass of a unit volume of a substance.Density unit: The unit of density is equal to the unit of mass divided by the unit of volume (density = mass / volume), and the most units of density are grams per milliliter, or grams per liter.The effect of temperature on density: Temperature is directly related to volume; Therefore, the density decreases with increasing temperature due to the increase in volume.Relation of body buoyancy to density:- If the weight of an object is less than the weight of water at the same size as the body when it is completely submerged in water, then the density of the body is less than the density of water, then the body will float until the weight of the object is equal to the weight of the displaced water.- If the weight of the object is greater than the weight of the displaced water when it is completely submerged, then it will be submerged in the water, and in this case the density of the body will be equal to its mass with the substance and the air it contains and will not float.You can evaluate the density measurement experiment on the Flappy platform from here
