Density is a measure of how much mass is contained in a given volume of a substance. It is often expressed as mass per unit volume, such as grams per cubic centimeter (g/cm3) for solids and liquids, and grams per liter (g/L) for gases.
The formula for density is mass divided by volume, or D = m/v. This means that to find the density of a substance, you need to know its mass and volume.
The density of a body is typically higher than the density of a liquid, as solids are more compact and have a higher mass per unit volume. However, there are some exceptions, such as ice being less dense than liquid water.
Density is an important property because it can help identify and distinguish between different substances. It is also useful in scientific experiments and engineering applications, as it can affect how a substance behaves under different conditions.
Generally, as the temperature of a liquid increases, its density decreases. This is because the particles in a liquid have more energy and are able to move further apart, resulting in a larger volume for the same mass. However, there are some exceptions, such as water becoming less dense as it freezes into ice.
