Best Answer

The simplest explanation is that air is composed of gases. Gases are composed of molecules. Molecules have mass. The closer molecules get to the center and bottom of the gravity well, the more closely packed they become, because successive "layers" pack down on those below, piling up. The weight of the gases on top of those on the bottom compress those on the bottom.

How do pressure differences explain destructive effects of a tornadoes winds?

The low pressure inside a tornado pulls air inward. This air accelerates to great speeds as it enters the tornado, though due to the spin not much of the air actually reaches the center. Generally lower pressure means faster winds, and thus more potential for damage.


Ideal gas law to explain why a hot air balloon floats?

We know from the ideal gas laws that when you heat a gas under constant pressure, it will expand. (In a hot air balloon, the air that is heated is not in a rigid container, but in a balloon that expands with the expanding gas; the pressure it is under is only the atmospheric pressure.) The expanded gas will then have a lower density and will therefore be bouyant in air, and therefore able to lift a balloon.


What effect does cold air have on air pressure?

Cold air increases air pressure


What is the relationship between altitude and air pressure to explain why rescue helicopters have a difficult time flying at altitude over 6000m.?

The higher you are from the Earth's surface - the lower the air pressure is. Helicopters are heavy machines - requiring a huge amount of effort from the rotor blades to keep it airborn. The lower the air-pressure, the harder the rotors have to work to keep the craft flying.

How does pressure explain why hurricanes and tornadoes have such high winds?

Wind, the movement of air, is driven by pressure differences. Like all liquids and gasses, air tends to move from an area of high pressure to one of low pressure. The more the pressure changes over a given distance, the faster the air moves. Both hurricanes and tornadoes have significantly lower pressure than their surroundings, which exerts a strong pull on the air.


How can lower air pressure make liquids evaporate faster?

You can explain this in a number of different ways. A high air pressure promotes the return of evaporated molecules to return to the liquid state, so a low air pressure is more amenable to the existence of evaporated molecules in the gaseous state.

Does Bernoulli's principle explain why planes fly?

Yes. Air that travels a longer distance over the more curved top surface of a plane's wing is at a lower pressure than air at the bottom. (Bernoulli's principle states that higher-speed air is at lower pressure.) Air flows from high to low pressure, and therefore the air on the underside of the wing pushes the wing upward toward the lower-pressure air above it, and the rest of the plane along with it.
