If the volume of an object were to double, with no change in mass, its density would? a) Halve b) Double c) Be the same d) None of these
The formula for density is
We need to double the volume, i.e. multiply it by
But in order to multiply one side of the equation by a number, the same has to be done to the other side.
Multiplying the volume by
So let's multiply both sides of the equation by
Therefore, doubling the volume results in the density being halved.
