Air is denser at lower altitudes and less dense at higher altitudes. If the bottom of the valley is directly below the mountain, at a lower altitude, then there is technically more air in the valley.
The air pressure would be greater at the bottom of the mountain because there is technically more air on top of you. The top of the mountain is higher up in the atmosphere, causing the air to be thinner and have less density, which leads it to having less air pressure.
There are fewer gas molecules in the mountaintop air.
Air pressue is low and more dense
Air pressure decreases as height is gained. There is less air pressure at the top of a high mountain, than at sea level.
When you are at a higher altitude, like on a mountain, you are farther up in the atmosphere meaning there is less air pressing down on you. When you are at a lower altitude, like at sea level, there is more air pressing down on you because there is more atmosphere above you.
Air pressure is greater at sea level because there is more air above that is pressing down. Any atmosphere is more dense at the surface of the planet than at locations higher in altitude. (Areas that are lower than sea level will generally have still higher atmospheric pressure.)
On a mountain, due to the high elevation, the air is thinner than at sea level, which makes it less able to hold heat.
The air at the top of the mountain is thinner than the air at the base of the mountain. That is why you are harder breathing on the top than on the bottom.The gases are about the same, but there is usually a lot less water vapor (because its cold) :but the pressure is less (that is, the number of molecules per cubic foot is less), down to the point that on top of the tallest mountains humans can not survive for any appreciable time.
Air pressure decreases as height is gained. There is less air pressure at the top of a high mountain, than at sea level.
no because at the top of the mountain its less pressure than at the sea level so it will take more time to boil
It is the effect of air pressure. The air pressure at the top of a mountain is less than the air pressure at sea level. The effect of air pressure on a water surface is to prevent or oppose water molecules escaping from the surface. The greater the air pressure, the more heat energy is needed to allow the water molecules to escape and so at sea level the water will boil at a higher temperature than if it were on top of a mountain.
Water would boil higher at the top of a mountain than at sea level. This is because there is less atmospheric pressure at higher elevations.
That would depend where you are. The weight of air above you is greater at sea level than up a mountain, but if you were in a plane it might well be less than up a mountain.
Air pressure decreases with altitude because there are fewer air molecules at higher elevations. As you climb a high mountain, the weight of the air above you decreases, resulting in lower air pressure.
The air pressure at the top of a mountain is lower than at the bottom due to the reduced weight of the air column above. This means there are fewer air molecules per unit volume at higher altitudes.
it is higher up on Mount Everest so it has less pressure than at sea level
There is less drag at altitude than at sea level. The air is thinner at altitude.
Water boils faster at sea level because there is higher atmospheric pressure, which increases the boiling point of water. At higher altitudes, such as on top of a mountain, the lower atmospheric pressure causes water to boil at a lower temperature, which means it takes longer to boil.
At higher altitudes, there are fewer air molecules above, resulting in lower atmospheric pressure. This decrease is due to the weight of the air above pressing down, and the effect is more pronounced at higher altitudes where there are fewer air molecules above exerting pressure.
The higher the elevation the lower the air pressure. Sea level is considered the standard for air pressure measurement.
