Each molecule bounces off an object pushing a little bit of force on that object. These add up to create the overall force. Imagine thousands of baseballs hitting a moving wall the balls will push the wall. This is basically a scaled up version of a demonstration of how pressure works.

What is the movement of air from high-pressure areas to low-pressure areas?
density
The measure of the force with which air molecules are pushing on the Earth's surface?
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi")
What happens to gas particles when air leaks out an inflated ball?
The gas molecules are constantly in motion, colliding with each other and the walls of the ball. The pressure inside the ball is also much greater than the pressure outside the ball. When there's a hole in the ball, the molecules keep colliding, and some make there way out through the hole. Remember that the molecules want to go to the area of lowest pressure so that they can be at equilibrium.
What creates pressure in a bicycle tire?
The pressure increases, and the molecules collide with the tire's inner surface.
How does wind exist?
Wind exists because of two main forces: The rotation of the earth, and the heat and light from the sun. The rotation of the earth causes wind because the natural tendency of air molecules is to stay still. The earth essentially is moving, and the air is essentially staying where it is, creating the illusion that the air is moving. This is called "the Coriolis Effect". The Coriolis effect is what causes the constant unchanging winds used by sailing ships. The heat from the sun is responsible for almost all of earth's weather, except for those mentioned above. The sun's heat causes the air molecules to become excited, and lack of heat makes the molecules stand still. Excited molecules expand, and create High Pressure. Still molecules contract and create low pressure. When high pressure air moves in to fill in the slight vacuum created by low pressure air, it creates wind. In short HOT AIR = HIGH PRESSURE COLD AIR = LOW PRESSURE HIGH PRESSURE TRIES TO GET TO WHERE THERE IS LESS PRESSURE.
What is it called when the movement of air molecules from an area of air pressure to an area of low air pressure?
Wind.
Air pressure is affected by temperature.?
Yes, air pressure is affected by temperature.When the temperature is higher the air pressure lowers and the weight of the air is lower. When air is warmer the molecules sperate and there are less molecules that can cause pressure.
Are movement of gas particles in the air against another object cause air pressure?
No
How is air pressure affected by temperature?
Yes, air pressure is affected by temperature.When the temperature is higher the air pressure lowers and the weight of the air is lower. When air is warmer the molecules sperate and there are less molecules that can cause pressure.
Air moves from which pressure systems towards which other pressure systems?
Air moves from high pressure systems toward low pressure systems. This movement is the cause for the winds.
How are molecules and air pressure connected?
Air pressure has molecules in it but other than that their is no connection
What cause the movement of the air?
Differences in air temperature and pressure usually cause wind, otherwise any kinetic energy can cause the movement of air. High pressure goes to low pressure, hot to cold. High temperatures have low pressures and low temperatures have high temperatures. Wind goes to low pressured areas to fill them in.
When air is heated air pressure decreases because the molecules?
when air is heated ,air pressure decreases because the molecules are
How does air pressure affect air movement?
Air pressure affects air movement because air moves from high pressure to low pressure. The air pressure pushes or will press the air around.
Does Cold Air Exerts More Pressure Than Warm Air?
In warm air, molecules are spaced farther apart. As air cools, molecular activity and movement slows down which cause compaction of the molecules. The increased density of air in the same space automatically increases the overall weight. That is why warmer air layers over cold air because the cold air is 'heavier' and sinks to the ground while the 'lighter', warm air rises.
Is gas particles in the air pressure?
Gas particles in the air contribute to air pressure. The molecules constantly collide with each other and with surfaces, exerting a force per unit area, which we perceive as pressure. The more gas particles present in a given space, the higher the air pressure will be.
What is up and down movement of air?
air molecules
