Answer:
Boyle’s Law, an inverse relationship exists between pressure and volume
Explanation:
We know that atmospheric preassure drops 1 mm Hg for every 10 m high.
And according to Boyle's Law, if <u>preassure decreases</u> <u>volume </u>will be<u> increased</u>.
Having in mind that density is the mass of anything ( air included) divided by the volume it occupies; if volume increases <u>density</u> will be <u>lower</u>.
So, lower pressure lower density
.
