Question

3. Summarize how density is changed by changing the mass without changing the volume, and by changing volume of a substance with out changing mass.

Answer 1

ill fan and medal please help

Answer 2

Here's a mathematical expression for density:
\[\rho =\frac{ m }{ V }\]
We can see that if we increase the mass (while volume remains constant) that density also increases!

Let's take m=10 and V=5

So we get \(\rho=10/5=2\)

Now what about if we change m to 15 instead of 10?
\(\rho=15/5=3\)

Therefore we say that the density is direction proportional to the mass and inversely proportional to volume
