Say for example you have an ice cube of which you need to find the volume..First find something that sinks in water..Next,dip it in water and find the volume of water it displaces..For this a Decanting Can might come in handy..Now tie the ice cube with a string of negligible mass and thickness to the mass that sank in water and lower it into water so that the ice cube is completely immersed in water..This time the volume of water displaced will be greater..Subtract the higher value from the lower and you have the volume of ice cube(or any other material for which you are to determine the volume)
A substance floats over another substance if it is less dense. Density is a measure of how much mass is in a given volume, so if one substance is less dense than another, it will float on top. This is due to the buoyant force exerted on the less dense substance by the denser substance.
In science, "less dense" means that a substance has a lower mass per unit of volume compared to another substance. This is commonly observed when an object or material floats in a more dense substance, such as when ice (less dense) floats on water (more dense).
Density is measured and expressed as the mass to volume ratio. To determine what the density of a substance you measure its mass and divide that number by its measured volume (or you can look up the density based on what composes it). Then, using the same units, do the same for another substance. The substance with the larger number is more dense, has more mass per volume, than the substance with the lower number, and the same in reverse with respect to less density.
There is no sensible answer to this question. A kilogram is a measure of mass while a cup is a measure of volume. The two measure different things and there is no direct conversion between the two. 4 kg of a dense substance will consists of a lot fewer cups than 4 kg of a less dense substance.
density is mass per unit volume so the less mass per cubic(what ever measure) the less buoyant.
52, assuming a density (weight per volume) equal to pure water. be definition, at standard room temperature and pressure, one cc of pure water = 1 gram of weight. but gram is a measure of weight only. cc = cubic centimeter = a measure of volume only. if the substance has a different density, the total cc may be less (more dense, a smaller volume water would be) or more (less dense, therefore a larger volume). the exact answer depends on the density of the substance being measured.
a measure of the compactness of a substance, expressed as its mass per unit volume. It is measured in kilograms per cubic metre or pounds per cubic foot.So, it means that ''more dense'' is the same as more compacted, and ''less dense'' is less compacted. As it is expressed per unit volume and measured in kilograms per cubic metre, signifies that an element that has more kilograms per cubic metre is more dense, more compact, resulting in more weight as well.
You are comparing their densities. Density is a measure of how much mass is present in a given volume. By comparing the masses of the same volume of different substances, you can determine which substance is more or less dense than the others.
If an object or substance is less dense than another, it will float on top of the denser object or substance. This is due to the principle of buoyancy, where the less dense material displaces an equal volume of the denser material, causing it to float.
its has more pressure
You can determine whether a solid substance is more or less dense than water by comparing their densities. If the density of the substance is greater than the density of water (1 g/cm^3), then the substance is more dense. If the density of the substance is less than the density of water, then the substance is less dense.
Density is a measure of mass per unit of volume. The higher an object's density, the higher its mass per volume. The average density of an object equals its total mass divided by its total volume. A denser object (such as iron) will have less volume than an equal mass of some less dense substance (such as water). The SI unit of density is the kilogram per cubic metre (kg/m3)
