A block of pumice stone, an iceberg, a log of wood, and so on. Thanks to H Z below, I never even thought of styrofoam.
one answer is a brick.A brick does not float on water.
Oil/petroleum (gasoline?) will float on top of water as well.
An example of a solid that floats on water is a needle, even though its density is greater than that of a water it still floats, this is because of Intermolecular Forces.Anything lighter (less dense) than water will float; this includes wood, some clothing, metal objects (like boats), provided they have enough air in between, etc.
When solids are added to water, they can dissolve, creating a solution. Alternatively, the solids may remain suspended in the water as a suspension if they are insoluble. In some cases, chemical reactions may occur between the solids and water, leading to the formation of new substances.
because of density
3 liquids- oil, water, and cleaning stuff can float on top of each other 3 solids- foil, paper, rocks
Generally, solids do not float on their own liquids; they typically sink if they are denser than the liquid. However, ice is an exception because it is less dense than water due to its crystalline structure, which creates more space between molecules. This lower density allows ice to float on liquid water, a unique property that has significant ecological implications for aquatic life.
The density of water is called "1.0" Certain objects have a mass greater than 1.0, therefore they will sink. Objects with densities less than 1.0 will float or remain partly submerged.
Un-answerable because there is no 'table 4' displayed in this question. Please rephrase.
To observe whether different solids float in a given liquid, you would use a clear container filled with the liquid, such as a graduated cylinder or a beaker. This allows you to see the solids' buoyancy and whether they sink or float. Additionally, a set of various solids to test, such as small weights or pieces of wood, should be used for comparison. It's important to ensure the liquids and solids are safe for the experiment.
Although you might think milk fats would likely float on water, milk also contains other solids like proteins and sugars, which make it barely heavier than water. So usually no - at the same temperature and pressure, ordinary homogenized cow milk would sink in water. A gallon of milk is heavier than a gallon of water.
no clouds are are a gas which is why they can float around freely in the sky.
