How do gas particles exert pressure on their container?
'This is because the air particles are bumpinginto each other and the walls. When this happens it causes pressure on the walls because of the speed the air particles are moving
Does air flow from areas of higher pressure to areas of lower pressure?
Air will flow from areas of high pressure to areas of low pressure. Pressure = force/area. So in this context, air pressure is the force the particles in that area exert on the space around them (let's imagine they're in a box). As air particles whizz around, they will collide with the edges of the box, so bouncing off and changing direction. This direction change involves a lot of acceleration (though speed may be the same, velocity (which is speed in a specific DIRECTION) will be very different. Physics tells us F=MA. Therefore, this acceleration will equate to a force on the outside world. This force will therefore be proportional to the number of particles in the area (more particles = more area). So, if an area of high pressure has lots of particles, there will be a spreading out of these particles to areas of low particles (diffusion, and energy's natural tendency to spread out). Alternatively, think of it as particles in the high pressure area pushing against the particles from the low area, and they're pushing force being greater, so they win! There you have a very long winded answer for why air moves from high pressure to low pressure!
The measure of force with which air particles push on matter?
The measure of force of gas particles against a surface is known as pressure (P). In SI units the force of gas pressure is in ATM(s) and Pascal's.
What happens to the particles of air inside a bottle as pressure is applied?
They begin to move quicker
Why does the air exert pressure on the surface of the earth?
Air produces a force on the surface of an object (in this case the earth) because of the movement of the particles that make up air. This force over a defined area is known as pressure.
What direction does the air in high pressure systems travel?
please improve Q. but if ur asking this, the air particles move in all directions, the more its under pressure, the more particles are moving.
How does air being heated affect the air pressure?
When air is heated the particles become excited and move and bounce off of surfaces causes pressure on it's container.
What does air move from?
air moves from particles to particles
When air warms air particles move closer together?
No. When air cools air particles move closer together. When air warms air particles move father away from each other.
How does air exert pressure using the particle model?
The attraction between gas particles is weak and the particles have large spaces between them. As the air molecules move around freely, they create pressure. Air has weight and that weight presses down on everything around us (creating pressure). Air is composed of molecules and exerts pressure. Air also experiences gravitational force.
Why does air pressure increase when you pump up a tire?
when you pump air into a tyre, the air particles move about and hit the wall of the tyre. As you pump more air into a tyre, more air particles hit the wall of the tyre.
How a soccer ball bounces?
A soccer ball bounces as the air particles in them hit and apply pressure at the ball, when it hits a surface, the pressure from the particles apply a force on the ball. Thus, making it bounce.
