explain

2. if the mass of an object stays the
-density as volume increases
-density as the volume decreases

1. If the volume of an object stays the same...

-mass increases as density increases

-mass decreases as density decreases

2. If the mass of an object stays the same...

-density decreases as volume increases

-density increases as the volume decreases

Explanation:

Density (d) = mass (m) / volume (V)

So in the firs case we can say V=m/d, so if the volume stay the same as the density increases then the mass will have to increases.

In the second case m= V x d, so if the mass stay the same the density has to change inversely proportionally to volume. So if the density increases then the volume has to decreases in order to conserv the same mass

the awnser is d you right bro
