Why is atmospheric pressure lower on the top of a mountain than it is 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.

When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
The gas pressure in the flask is lower than the atmospheric pressure when the water level is higher inside than outside the flask.
What is dependency of pressure and boiling point?
As air pressure drops over the water surface the boiling point will drop and vice versa. So a kettle of water will boil at a lower temperature at the top of a mountain than at sea level because there's lower air or atmospheric pressure at the mountain top. Pressure is proportional to boiling point
If you performed a melting point experiment in the laboratory and on the top of the mountain would your results differ explain?
Yes because the atmospheric pressure at mountain is lower, therefore m.p becomes lower
Why would water boil at less than 100 degrees on top of a mountain?
The boiling point of any liquid is the temperature at which its vapor pressure becomes equal to the atmospheric pressure. So if the atmospheric pressure is lower, it will take a lower temperature to make the vapor pressure equal to that of atmospheric pressure. At hill-stations, the air is generally thinner due to the altitude and the atmospheric pressure is also lower. Here, it requires less than 100oC temperature to reach the point where the vapor pressure of water reaches that of air. So, water boils below 100oC at hill stations.
How does atmospheric pressure change with height above sea level?
Atmospheric pressure is the weight of the air above the surface of the earth. As elevation increases, there is less air above the location and the pressure is lower. At sea level the column of air above the area is greater.?æ
If you boil water at the top of a mountain would you expect it to boil at 100 degree Celsius explain?
Yes. In general, higher altitudes mean lower atmospheric pressure. Lower atmospheric pressure means lower boiling points.
Why does water boil at a lower temperature on a mountain than sea level?
The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
How does atmospheric pressure change as you go from the top of a mountain to sea level?
It increases the lower you go in the atmosphere. In simple terms, there is more air pushing down on lower altitudes. Pressure will, of course, vary with weather conditions.
How do you think boiling of water will change on sea level as compared to boiling water on a mountain top?
I think that the temperature required to boil water is lower at high altitudes (where the atmospheric pressure is lower) than at sea level.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
The gas pressure in the flask is lower than the atmospheric pressure when the water level is higher inside than outside the flask.
Why doeswater boil at a low boiling point on top of a mountain and a higher boiling point in a pressure cooker?
This is because the boiling point of any fluid increases as the pressure acting on it is increased. Atmospheric pressure on top of a mountain is lower than normal atmospheric pressure. Conversely, by not allowing steam to escape, the pressure above the water in a pressure cooker is allowed to build up to a much higher level.
What is dependency of pressure and boiling point?
As air pressure drops over the water surface the boiling point will drop and vice versa. So a kettle of water will boil at a lower temperature at the top of a mountain than at sea level because there's lower air or atmospheric pressure at the mountain top. Pressure is proportional to boiling point
What is the relationship of boiling point with atmospheric pressure?
The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, atmosphere
Predict whether water would boil on top of a mountain at a higher or lower temperature than at sea level?
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.
Why did your thermometer never hit 100 degrees Celsius when boiled?
You are probably above sea level so that the atmospheric pressure is lower than sea level pressure. Water boils at lower temperatures as the pressure is lowered. The other possibility is that the thermometer is not calibrated correctly, but I'd go with the atmospheric pressure is below sea level pressure.
What would happen to the air pressure if you took a barometer from a mountain top down into a mine shaft?
the atmospheric pressure on top of a moutain would be lower than the atmospheric pressure down in a mine shaft
When air pressure decreases the mercury in a barometer?
The mercury rises. The lower atmospheric pressure allows the mercury to drop in level.
