You might double check your question. Graphite is a carbon compound with a density estimated between 2.09–2.25 g/cc, and thus it has higher density than water and will sink. Graffiti is typically paint, but it can also include surface scratches and etc. Without better specification it would be hard to specify a density. However, dry paint may have a density of 3-4 g/cc which is also higher than water.
No, the density of antimony is more than six times greater than the density of water so it will sink in water.
Zinc is more dense than water. The density of zinc is about 7.14 g/cm^3, whereas the density of water is 1 g/cm^3.
No, a magnet is not more dense than water. Density is the measure of how much mass is contained in a given volume, and the density of water is greater than that of most metals, including magnets.
100g of lead would occupy a larger volume compared to 100g of water because lead has a higher density of 11.34 g/ml, whereas water has a density of 0.995 g/ml. The higher the density of a substance, the more mass it can hold in a smaller volume.
chloroform has the greater density.Chloroform is a colorless liquid too.
Water
No, it depends on the volume of water that can dissolve the salt. If the volume of water is more then it dissolves more salt and the density will be more and if the volume of the water is less then it dissolves less salt and the density will be less.
That indicates that the average density of an egg is greater than the density of pure water but less than that of salt water. Salt water has more density the regular/pure water and the more salt you add the more it floats.
It's because of the density of the object; for example wood floats in water because its density is less then the density of water, and metal sinks because its density is more then the density of the water.
Paper clips have a density greater than the density of water.
For floating in water: density under 1 g/cm3 For sinking in water: density more than 1 g/cm3
salt water
ice floating on top of water because water has more density than ice.
When you cool water its density will increase as it will become more dense.
The density of water increases with depth due to the increase in pressure. As water molecules are packed closer together under high pressure, the density of water increases. Therefore, in deep water where the pressure is higher, the density of water is also higher.
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
I can only assume that you mean which has the grater desity water or boiling water. The colder the water the more density it will have.
