It doesn't pump air out; it forces water out of its ballast tanks to increase its buoyancy.

When a submarine pumps water out of its floatations tanks its density decreases and it floats Why does its density decrease?
Because the tanks are filled with air afterwards. Air has a lower density than water.

Because the tanks are filled with air afterwards. Air has a lower density than water.
How do submarines control their density?
By their pumps and ballast-tanks: allowing water into the tanks to raise the vessel's density so can submerge, or pumping air into the tanks to displace the water and allow the submarine to surface.
Does cold air increase or decrease water density?
decrease
How do you decrease the density of air?
Keep it dry.

Because the tanks are filled with air afterwards. Air has a lower density than water.
When altitude increases does air density?
The density of the atmosphere decreases with altitude.
How does the density of air increase or decrease?
By Removing or addng heat
Why does density of air decrease with increase in height?
The density of air decreases with increasing altitude because air at high altitudes is under less pressure.
As a parcel of air increases in altitude its pressure will?
No, the density lowers. When air expands, the volume of area it takes up increases while the density decreases. The molecules move apart.
