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.
Air pressure decreases as height is gained. There is less air pressure at the top of a high mountain, than at sea level.
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.)
Temperatures decrease with altitude due to a decrease in air pressure. As you ascend a mountain, the air becomes less dense, leading to a reduction in the amount of heat that can be retained. This results in colder temperatures at higher elevations compared to 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 can be modeled as column in that the lower the column regards the more of it pressing down upon you. Therefore, someone standing at sea level has a more air pressure pushing down on them then someone at high altitude (as in a mountain).
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 on earth results from the earth's gravitational pull on the earth's atmosphere. In some sense, pressure results from the weight of the air above the point at which one measures pressure. At higher altitudes, there is less air above, resulting in less weight, which translates into pressure.
Air pressure decreases as height is gained. There is less air pressure at the top of a high mountain, than at sea level.
The higher the elevation the lower the air pressure. Sea level is considered the standard for air pressure measurement.
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.)
Temperatures decrease with altitude due to a decrease in air pressure. As you ascend a mountain, the air becomes less dense, leading to a reduction in the amount of heat that can be retained. This results in colder temperatures at higher elevations compared to sea level.
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.
The boiling point of water decreases at higher altitudes because the atmospheric pressure is lower. At lower pressure, molecules in the water can escape into the air more easily, requiring less heat to bring the water to a boil. This means that water will boil at a lower temperature on top of a mountain than at sea level.
