Answer: The correct options are:
<em>exerts more pressure as it increases
</em>
<em>measures how tightly molecules are packed
</em>
<em>equals mass divided by volume</em>
Explanation:
Air density can be described as mass per unit of volume of the volume of air.
As the altitude increases, the air density tens to decrease. Hence, option A is not correct.
The density of the air determined how many atoms of air can occur in a particular volume, In other words, it determines how tightly or loosely atoms of air are packed in a particular volume.
Hence, when the air density will increase, the molecules will be more tightly packed and the pressure will be more.
