Can anyone explain why pressure at the top of a mountain is lower than pressure at sea level?..

air has weightCan anyone explain why pressure at the top of a mountain is lower than pressure at sea level?..
Why cant we answer this question on the basis of temperature?Temperature at the top of a mountain is lower than temp. at sea level.So molecules will more kinetic energy at sea level and will apply greater force hence greater pressure.:/air has weight
as you move upwards there are less air particles ABOVE YOU being pulled by gravity
Also, on a mountain top, you are away from the center of earths gravity so the air weighs less at that height.
Then the question arises why is it cold at higher altitude? It goes this way its cold because there is less pressureWhy cant we answer this question on the basis of temperature?Temperature at the top of a mountain is lower than temp. at sea level.So molecules will more kinetic energy at sea level and will apply greater force hence greater pressure.:/
it does more the temperature more the pressureI don't think that temperature affects the pressure of air in anyways. And moreover kinetic energy also has no direct relation with pressure.
Exactly!it does more the temperature more the pressure
what is pressure?continuous physical force exerted on or against an object by something in contact with it.
when you increase Kinetic energy more molecules start exerting force on the walls of a container hence higher pressure
yes but why does the temperature change?Ahhh!.....im confused.As far as i know temperature does affect the pressure because as temperature increases the vibration and movement of molecules increases and so the frequency of collisions and the force they exert increases.
Okay i get it.But how can low pressure cause a low temperature at the top of the mountain? that can also be a good questionyes but why does the temperature change?
You aren't getting what i am saying
let me take an example i switched on the AC because it was hot
this doesn't mean It became hot when i switched on the AC
do you get it?
the reason there is low pressure is not because of low temperature
the reason there is low temperature is because of the low pressure
and so the reason there is low pressure is because of less air (weight) as i explained before
yeah it can beOkay i get it.But how can low pressure cause a low temperature at the top of the mountain? that can also be a good question
Exactly!is a mountan/quote]
Lets take example of two cities quetta and karachi quetta Is a valley and has mountains mountains have hieght and something which has height less air would be there above it so less pressure hence quetta is cold
if we take example of karachi its at sea level means not at hieght which means more air above the area that means pressure will automaticall increase because of more air henxe temp will increase
ofcourse!yeah it can be
do yo want me answer this?
lol i though you got itofcourse!
the same this but this caseit does more the temperature more the pressure
what is pressure?continuous physical force exerted on or against an object by something in contact with it.
when you increase Kinetic energy more molecules start exerting force on the walls of a container hence higher pressure
where did you get this question from or was it just a random one?i got it i got it i got it!!!...phew! thanks zainab..thank u very much
it was a past paper question.I don't remember the year.It was in between year s05 and w13. keep searchingwhere did you get this question from or was it just a random one?
lol maybe i will come across it some timeit was a past paper question.I don't remember the year.It was in between year s05 and w13. keep searching
Pls do share questions that u find confusing.It will really help us.lol maybe i will come across it some time
I willPls do share questions that u find confusing.It will really help us.
