What happens to boiling point above sea level?
As you go above sea level, the atmospheric pressure decreases, and so the boiling point also decreases to below 100ºC.
Would you expect the air pressure in a valley that's below sea level to be higher or lower than air pressure at sea level?
Air pressure in a valley below sea level would be higher than at sea level. This is because the weight of the air column above is greater in the valley due to the higher density of air molecules compressed into a smaller volume.
What is the Boiling point of water at 1800 m above sea level?
At 1800 meters above sea level, the boiling point of water is around 93.5°C due to the lower atmospheric pressure.
Why does diving 30m below sea level affect our bodies more than being in a building 30m above sea level?
Diving 30m below sea level increases the pressure on our bodies due to water above compressing our lungs and tissues more. In contrast, at a building 30m above sea level, the pressure is decreasing compared to sea level, but the effects on the body are negligible in most cases. The change in pressure underwater can lead to issues like decompression sickness if not managed properly.
What happens to the boiling point of water at altitudes above sea level?
The temperature decreases the higher you go.
Where is the air pressure the greatest at sea level or ona mountaintop explain?
Air pressure is greatest at sea level because the weight of the atmosphere above compresses the air, increasing its density and pressure. As altitude increases, such as on a mountaintop, there is less air above to exert pressure, resulting in lower air pressure. Therefore, sea level has a higher concentration of air molecules and greater pressure compared to higher elevations.
What is the pressure above sea level in mmHg?
The atmospheric pressure at sea level is typically around 760 mmHg. As you increase in altitude above sea level, the atmospheric pressure decreases. For example, at 5,000 feet above sea level, the atmospheric pressure may be around 625 mmHg.
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
Why is the pressure at 14000 ft above sea level 0.69 ATM while the pressure at 14000 ft below sea level is 470 ATM?
The pressure at different altitudes depends on the weight of the air column above that point. At 14000 ft above sea level, there is less air above causing lower pressure (0.69 ATM). Conversely, at 14000 ft below sea level, there is more air above causing higher pressure (470 ATM).
Where is the pressure higher above the sea or above the land in coastal areas at night?
Above the sea level
Why is air pressures greatest at ground level?
Air pressure is greatest at ground level because the weight of the air above compresses the air molecules closer together, creating higher pressure. As altitude increases, there is less air above, resulting in lower air pressure.
What happens to atmospheric pressure as you move up away from sea level?
As altitude above seal level increases, atmospheric pressure decreases.
At 18000 feet above sea levelthe air density is 12 that at sea level What is the atmospheric pressure at this altitude?
The atmoshperic pressure at 18,000 feet above sea level is 280 mm Hg.
What would you use to measure the elevation above sea level on air temperature and air pressure?
elevation above sea level . . . barometer or GPS air temperature . . . thermometer air pressure . . . barometer
How is pressure here different from pressure at sea level?
It depends on what you mean by "here", but at any location above sea level, aveages pressure where you live will be lower than it is at sea level. The higher up you live, the lower the aveage pressure.
Which altitudes would have the lowest air pressure and why?
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
Why does atmospheric pressure becomes greater above sea level?
Atmospheric pressure decreases with increasing altitude because the weight of the air above a given point decreases as you move higher in the atmosphere. At sea level, there is a greater column of air pressing down, resulting in higher pressure. As you ascend, there is less air above you, leading to lower pressure. Therefore, atmospheric pressure is greater at sea level compared to higher elevations.
