Vapor density refers to the density of a vapor compared to the density of air at a given temperature and pressure. It is commonly used to compare the weight of a vapor to an equal volume of air, which can help in understanding how it will disperse in the atmosphere.
Each gas has a specific density at a given temperature and pressure.
The expression "vapour density of gas" is not correct.
It is the pressure exerted by vapors of a substance in equilibrium with liquid form of the substance. It depends upon- Nature of the liquid, temperature, and boiling point.
A definition doesn't exist for low density. The values depends on the application or material.
A definition of lower density doesn't exist. Solids with densities under 1,00 g/cm3have a very low density.
The definition of density is mass divided by volume.
the DICKNESS of the liquid
Density is an intensive quantity which means it is independent of size. This can be seen from the definition of density. Density = mass/volume So if the sample size increases than so does the mass, but the density remains unchanged.
