At room temperature, the density of sodium is slightly less than that of water and it will, briefly, float (briefly, because it will be rapidly reacting with the water, and may in fact be on fire at the time).

How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.
What density does an object have to have to sink in water?
A density greater than that of water (which varies with temperature).
Why is the density of ocean water greater than tap water?
because salt is higher density than water and dissolves in the water, increasing density
Is the density of 8 mL of water greater than equal to or smaller than the density of 4 mL of water?
It depends upon the temperatures and purity of the two quantities of water. If they are both at the same temperature and both have the same purity, they will both have the same density as density does not depend upon the volume, but the substance itself. If they are at different temperatures, or have different purities, then they will have different densities, but which would be greater would depends upon which has which temperature and which purity.
Why does seawater have a greater buoyant force than fresh water?
Seawater has a greater buoyant force than fresh water because seawater has a higher density than fresh water therefore the buoyancy is higher. *Improved* This happens because when water mixes with the salt in sea water, the density changes to the average density which is around 1.55 g/mL (Average density is the density of different materials put to together )
Why does sodium sink in water?
Sodium shouldn't sink in water at room temperature, because the density of sodium is less than the density of water. The density of sodium at room temperature is 0.968 g/cm3, whereas the density of water at room temperature is 0.998g/cm3. So technically, sodium should float in water, not sink.
What is density of sodium silicate?
The density of sodium is rho = 968 kg/m3 or rho = 0.968 g/cm3.
Which has greater density ice or water how can you say that?
Water has a greater density than ice.
Why does sodium chloride sink?
1. Because the density of sodium chloride is higher than the density of water. 2. Sodium chloride is soluble in water.
Does freshwater or saltwater have a greater density?
Salt water has a greater density.
Why is chloroform at the bottom during extraction process with benzoic acid and sodium chloride mixture in water?
Because it is immiscible and has a greater density.
How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.
What has a greater density 3kg water or 7kg of water?
Same density.
What density does an object have to have to sink in water?
A density greater than that of water (which varies with temperature).
If an object sinks when being placed in water its density is?
To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.
Which has the greater density water or ice?
Water
The density of water is equal to 1.0 gcm3. A substance with density equal to 2.1 gcm3 would in water.?
A substance with density equal to 2.1 gcm3 it's sinking in water.
