To find the density of a liquid, you need to measure its mass and volume. The formula for density is density mass/volume. First, measure the mass of the liquid using a scale. Then, measure the volume of the liquid using a graduated cylinder. Finally, divide the mass by the volume to calculate the density of the liquid.

What is the SI units for density in liquids?
The SI unit for density in liquids is kilograms per cubic meter (kg/m^3).
How does density affect the position of different liquids in a container?
liquids with higher density will sink to the bottom of a container, while liquids with lower density will float on top. This is due to the principle of buoyancy, where denser fluids displace less dense fluids. The positioning of different liquids in a container is determined by their relative densities.
Why hot liquids float above cool liquids?
Hot liquids have lower density than cooler liquids because the heat causes the molecules to spread out, making them less dense. This difference in density causes the hot liquid to float above the cool liquid because objects with lower density float on top of objects with higher density.
How does density relate to liquid layers?
Density is a key factor in the formation of liquid layers because liquids with different densities will stratify based on their density, with denser liquids sinking below less dense liquids. This phenomenon is known as stratification, and it occurs naturally in various environmental conditions, such as in ocean layers or in lakes. Density differences cause liquids to separate and form distinct layers.
Describe how you can determine the relative densities of liquids?
Water has a density of 1 g/cm3 , which means that for every cubic centimeter of water, it will weigh 1 gram (at normal atmospheric pressure and normal earth gravity) To find the density of a liquid, or in fact any substance, divide its weight by its volume.
