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 else can I help you with?
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.
Does air pressure eventually cause a thermal to dissipate?
Air pressure itself does not cause a thermal to dissipate. However, changes in air pressure can affect the movement of air molecules and impact the distribution of heat in a thermal system. This can lead to changes in temperature gradients and affect the dissipation of heat.
What is the movement of air molecules brought about by a source of vibration?
The movement of air molecules brought about by a source of vibration is known as sound. When an object vibrates, it creates fluctuations in air pressure, causing nearby air molecules to vibrate and transmit sound waves through the air.
Are movement of gas particles in the air against another object cause air pressure?
No
What do air molecules bounce off of?
Air molecules bounce off of other air molecules, as well as off of surfaces such as walls and objects. This bouncing results in the pressure and movement of air that we feel as wind and turbulence.
What do changes in density cause air movement?
Changes in density cause air movement because air tends to move from areas of higher density to areas of lower density. This movement occurs to equalize the pressure differences caused by the density variations, leading to the flow of air molecules. This process is known as convection.
How does friction between the ground and molecules in the air affect winds near the earhts surface?
Friction between the ground and air molecules slows down the movement of air near the Earth's surface, creating areas of high pressure. This can cause surface winds to flow from areas of high pressure to low pressure, resulting in the formation of wind patterns.
How does wind affect air pressure?
Wind affects air pressure by moving air molecules from areas of high pressure to areas of low pressure. As the wind blows, it creates changes in air pressure by redistributing the air in the atmosphere. This movement of air helps to equalize pressure differences and create weather patterns.
How are molecules and air pressure connected?
Air pressure has molecules in it but other than that their is no connection
What is the force that opposes the movement of the object in the air?
Air resistance, also known as drag, is the force that opposes the movement of an object in the air. It is caused by the friction and pressure of air molecules on the surface of the object as it moves through the air.
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.
