What difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
Does density depend on the amount present?
No, density is an intrinsic property of a material and does not depend on the amount present. Density is defined as mass per unit volume, so it remains constant regardless of the quantity of the material.
What is the density of a vacuum?
The density of a vacuum is essentially zero because it contains no matter. In a perfect vacuum, there are no particles present to contribute to a measurable density.
What does density compare?
Density compares the mass of an object to its volume, showing how tightly packed the particles are within the object. It indicates how much matter is present in a given space, with higher density meaning more mass is concentrated into a smaller volume. The formula for density is density = mass/volume.
