Answer:
The correct answer is B)equals mass divided by volume.
Explanation:
=> Air density reduces with increase in altitude. Air becomes thinner and thinner.
=>As air density increases, the number of molecules present per cubic meter of air increases, the number of molecules striking a body per unit area of it increases, hence the pressure also increases.
