Relative Density
Relative density, also known as specific gravity, is a measure of how heavy a substance is compared to water. It’s calculated by dividing the density of the substance by the density of water at the same temperature. If the relative density is greater than 1, the substance is heavier than water and will sink; if less than 1, it is lighter and will float. This measurement helps in understanding a material’s buoyancy and properties without needing to know its exact density, making it useful in fields like geology, engineering, and material science.
