Gas particles that are not contained will always move from an area of?
higher concentration (pressure)
What happens to gas particles when air leaks out in an inflated ball?
Gas particles travel from an area of higher pressure to lower pressure when air leaks out of an inflated ball.
What is the force caused by particles hitting a certain area?
Pressure. It is measured as a given force applied over a given area.
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
How do you find pressure if force and area is given?
force= pressure*area
Gas particles that are not contained will always move from an area of?
higher concentration (pressure)
What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure?
As air pressure in an area increases, the density of the gas particles in that area decreases.
How does increasing the number of particles of a contained gas it's pressure?
Pressure is defined as the force per unit area applied. This force is derived from the collision of particles. Pressure increase when this force is increase, and it applies otherwise too. By increasing the number of particles in a specific amount of gas, there are more particles colliding onto the container. This causes the force per unit exerted by the gas on the container to increase. As such, when one increases the number of particles within a container of gas, the pressure within the container will increase.
How does wind erosion occur?
"How" because wind is in a high pressure area looking for a low pressure area so that is how the wind moves. When it moves it is always picking up "trash"(small particles of sand and dirt).
What is produced from an area of high pressure to an area of low pressure?
Diffusion occurs when an area of high pressure meets an area of low pressure. They mix together and create an equilibrium, all particles spread out equally.
Why is there no such thing as sucking?
Because the "sucking" is actually pushing. For example. When there is an area of low pressure, air appears to get sucked into it, but actually it is being pushed by the air behind it. This is because air particles are in motion, and therefore posses energy. Some have more and some have less energy, but there is always a net. Most of this energy is kinetic energy, and the amount of particles dictate how many collisions there are between particles, and in the collisions particles move until they hit another particle. So, if there are less particles in the low pressure area to collide with, particles end up staying there longer than in the higher pressure area until equilibrium is reached. So, in effect the air particles are pushing other air particles to an area where they aren't being pushed.
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!
What happens to gas particles when air leaks out in an inflated ball?
Gas particles travel from an area of higher pressure to lower pressure when air leaks out of an inflated ball.
In which direction does cool air move by water?
It will always move from an area of higher pressure to an area of lower pressure.
Does air pressure increase when temperature does?
Air pressure actually decreases as you reach higher altitudes because gas particles in the air expand, making the air colder and less dense.
What is the force caused by particles hitting a certain area?
Pressure. It is measured as a given force applied over a given area.
