Why was mercury chose for a job in barometres?
Pressure in these things is measured by how tall a column of liquid it can support. Now atmospheric pressure can support many feet of oil, for example, and who wants a barmeter that tall? Mercury is very dense so you can get away with less than a metre high. Problem solved.
What would happen to an orange in space?
In the vacuum of space, an orange would freeze and dehydrate quickly due to the lack of atmospheric pressure. Without air pressure to keep the water in the orange from boiling off, the fruit would dry out from the exposed water vapor. Eventually, it would become shriveled and freeze-dried.
How far away can you see a candle?
under ideal conditions about 3 and a half miles
Why is there no rainfall on Mars?
Mars has a very thin atmosphere that is mostly composed of carbon dioxide. The low atmospheric pressure, coupled with the lack of a strong magnetic field, allows solar winds to strip away any liquid that may form on the surface, making it difficult for rain clouds to develop and sustain precipitation.
Why do things appear lighter the further away they are?
Objects appear lighter the further away they are due to atmospheric perspective, where the atmosphere scatters light and reduces contrast as distance increases. This makes objects appear lighter and less distinct as they recede into the distance.
Does the atmospheric pressure increase or decrease as you move upward away from sea level?
Atmospheric pressure decreases as you move upward away from sea level due to the decrease in the weight of the air above pushing down. This means that atmospheric pressure is lower at high altitudes and higher at lower altitudes, such as at sea level.
How does atmospheric pressure change as you move up away from sea level?
as you move up from sea level, the atmospheric pressure decreases. At higher elevations, theres less air above you so therefor less air pressure. When the air pressure outside your body decreases, the air pressure inside also decreases (slowly).
How does atmospheric pressure change as you move away from the surface of earth?
Atmospheric pressure decreases as you move away from the surface of the Earth. This is because the weight of the air above you decreases with higher altitudes, resulting in lower atmospheric pressure.
How does the atmoshpheric pressure change as you mve up away from sea level?
Atmospheric pressure decreases as you move up away from sea level. This is because there is less air above pushing down on you the higher you go. This change in pressure can lead to lower oxygen levels at higher elevations.
What can change the boiling point of water?
The boiling point of water can be affected by changes in atmospheric pressure. At higher altitudes where the atmospheric pressure is lower, the boiling point of water is lower. Conversely, at lower altitudes with higher atmospheric pressure, the boiling point of water is higher.
What happens to air pressure when you move upward away from sea level?
Air pressure decreases as you move upward away from sea level due to a decrease in the weight of the air above. This decrease in pressure can cause discomfort in the ears and reduce the availability of oxygen for breathing at higher altitudes.
The atmospheric pressure near the earths surface does what?
It decreases as you move away from the earth surface
Where is atmospheric pressure maximum and why?
A saxophone is playing a steady note of frequency 210 Hz. The temperature in the room is 25 C. Suppose that, at some instant, the varying pressure at your eardrum is at a maximum. How far away (in meters) is the next pressure maximum? If anyone can help me with this, I would appreciate? The speed of sound at 25 C = 343m/s wavelength = speed of sound / frequency wavelength = 343m/s / 210/s = 1.6m Therefore, the distance of the next pressure maximum is 1.6m away from your ear drum.
Will the atmospheric pressure be more at the sea level or on a hill?
In general, on a hill. However, there are hills in places like Death Valley that are lower than sea level, so there are exceptions. This answer does not take other meteorological conditions into account. Barometric pressure at sea level in a hurricane can be much lower than on a hill miles away.
What happens to air pressure as its moves away from earth?
As air rises away from Earth's surface, air pressure decreases due to the lower atmospheric density at higher altitudes. This relationship is known as the "lapse rate," where air pressure decreases with increasing altitude.
Why on a windy day does atmospheric pressure decrease?
Because you are ugly. Because you are ugly.
what are the dependent and independent variables of a ballon depending on atmospheric pressure?
The mass of the balloon is independent. Atmospheric pressure will not change this because atoms are not being added or taken away from the balloon itself or its contents. The volume of the balloon will change, however, as it will expand or compress in response to the atmospheric pressure around it. The volume, therefore, is a dependent variable in this situation.
