write a few sentences summarizing how density is changed by changing the mass without changing the volume and by changing the volume of a substance without changing the mass (both by increasing and decreasing). if you prefer, you can use specific numbers and calculations to show the relationship instead.

Explanation:

Since density is calculated with mass divided by volume, changing either of these variables will affect the density, not necessarily both of them. If only the volume is increased or only the mass is decreased, the density will decrease. If only the volume is decreased or only the mass in increased, the density will increase.

Example:

Original density is 50g/ml. Mass is 50g and volume is 1ml.

Increase mass only:

mass = 100g

Density = 100g/ml   <= Density is increased

Decrease mass only:

mass = 25g

Density = 25g/ml   <= Density is decreased

Increase volume only:

volume = 2ml

Density = 50g/2ml = 25g/ml   <= Density is decreased

Decrease volume:

volume = 0.5ml

Density = 50g/0.5ml = 100g/ml   <= Density is increased
