WebOct 9, 2024 · Law of Flotation: Materials whose densities are lower than that of the liquid they are immersed in will float on that liquid. Wood and oil float on water, as the density of water is higher than the density of wood and oil. According to Archimedes' principle, the design of a ship must ensure that it can displace water equal to the ship's own weight. WebDensity is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will …

WebThe density of a liquid is a measure of how heavy it is for the amount measured. If you weigh equal amounts or volumes of two different liquids, the liquid that weighs more is more dense. If a liquid that is less dense than water is gently added to the surface of the water, it will float on the water. If a liquid that is more dense than water ...
