changing the mass or volume of an object changes its density and ?
changing the mass or volume of an object changes its density and not its inherent properties. Density is defined as the amount of mass per unit of volume. When you change the mass or volume of an object, its density will inevitably be affected.
To get the density of an object, you need two values: its mass and its volume. The formula for density (ρ) is:
ρ = mass / volume
So, if you know the mass and volume of an object, you can divide the mass by the volume to find its density. Alternatively, if you know the density and either the mass or volume, you can rearrange the formula to solve for the missing variable.
For example, let's say you have a cube with a mass of 100 grams and a volume of 20 cubic centimeters. You can calculate its density as follows:
Density (ρ) = Mass / Volume
Density (ρ) = 100 g / 20 cm^3
Density (ρ) = 5 g/cm^3
In this case, changing either the mass or the volume of the cube will alter its density. If you increase the mass while keeping the volume constant, the density will increase. On the other hand, if you increase the volume while keeping the mass constant, the density will decrease.
