Question

How does gas pressure change with volume?

Answer 1

Well, what does old `"Boyle's Law"` say...

Explanation:

`Pprop1/V`...pressure is INVERSELY proportional to volume.

And so `PV=underbrace(k)_"some constant"`...and under different conditions...with TEMPERATURE constant...

`P_1V_1=P_2V_2`...
