If you meant to ask what elements would float in air, the density of air is about 1.2 g/L. Wood that is less dense and floats has big openings. So they would float, but you would have to put them into the water as bubbles. Thick sap requires big openings to flow through, while thin, watery sap needs only small openings. A cube of unknown material and uniform density floats in a container of water with 60 of its volume submerged. These openings allow tree sap to run through the tree. The density is determined by the size and number of openings in the wood. Unlike the other two examples, this dense wood sinks all the way to the bottom when placed in water.īut why is some wood less dense than others? It still will float, but some of the wood is submerged into the water.Ī third type of wood, called ipe, is from a tree that grows in Central and South America. Oak, on the other hand, is a much heavier piece that’s often called a hardwood. A piece of cedar, which is rather light, will easily float on top of water. As water cools and freezes, it becomes less dense due to the unique nature of hydrogen bonds. Water, however, reaches its maximum density at 40º F (4.4º C). The density of the liquid is: 9 times more than that of water 2 times more than that of water 3 times more than that of water 1. The fact that ice floats in water is a bit strange, because most substances are denser when theyre solids. The same body floats in a liquid with one-third volume immersed. Testing out a few samples of wood illustrates this. A body floats in water with its one-third volume above the surface. The logs that float are less dense than the logs that sink. An object that is more dense than water will sink. An object that is less dense than water can be held up by water, and so it floats. This ratio between weight and volume is called density. So does one cubic inch of wood weigh more or less than one cubic inch of water? The answer depends on the type of wood and determines whether that wood would float or sink. If an object weighs less than an equal volume of water, it floats because the water can support its weight. If an object of a certain volume weighs more than an equal volume of water, it sinks because the water can’t hold it up. Whether an object floats or sinks in water is determined by the ratio of its weight compared to its volume.
