What generally happens to atmospheric pressure on a windy day?
On a windy day atmospheric pressure decreases because the higher the wind velocity, the lower the air pressure, or atmospheric pressure. This is how chimneys work, the air that moves above the chimney causes low air pressure because of the high wind velocity compared the velocity of the air inside a house. The air inside the house goes towards the low air pressure and takes the smoke with it.
Explain why drinking through a straw shows that fluids flow from areas of high pressure to areas of low pressure?
Drinking through a straw creates a suction that lowers the pressure inside the straw. This decrease in pressure compared to the higher pressure outside the straw causes the liquid to be pushed up and flow towards the lower pressure area inside the straw. This demonstrates the principle that fluids naturally flow from areas of high pressure to areas of low pressure to equalize the pressure difference.
How does atmospheric pressure distribute energy around the globe?
Changes in pressure cause wind to blow. This facilitates some energy transfer through the atmosphere through eddy propagation, for example, this also facilitates the movement of air masses and cyclones across latitudes.
Is refraction an area of low pressure?
No, refraction is not an area of low pressure. Refraction is the bending of light as it passes through different mediums with varying densities. On the other hand, low pressure refers to a region where the atmospheric pressure is lower than the surrounding areas.
A balloon carrying weather instruments is released at Earth's surface and rises through the troposphere as the balloon rises what will the instrument generally indicate?
As the balloon rises through the troposphere, the instrument will generally show a decrease in temperature and pressure with increasing altitude. The decrease in pressure will be more pronounced, leading to a drop in atmospheric density.
How is pressure related to drinking through a straw?
"Muscular action reduces air pressure in the mouth, whereupon atmospheric pressure forces the drink up the straw." ~ Wikipedia
How does air pressure help drinking through a straw?
when you drink through a straw you remove some of the air in the straw. Because there is less air pressure of the straw is reduced. But the atmospheric pressure on the surface of the liquid.
Why can't we suck a cold drink through a straw on the moon?
Sucking through a straw relies on atmospheric pressure to push the liquid up. In the airless environment of the moon, there is no atmospheric pressure to assist in the suction action, making it impossible to drink through a straw.
How is drinking through a straw related to vacuuming?
It is simply creating a low pressure
When cold air moves into an area the atmospheric pressure is?
When cold air moves into an area, the atmospheric pressure is high because cold air is denser than warm air. When a cold front moves through an area, the pressure always rises.
Why do a weather balloon keep increasing in volume as it rises through the stratosphere?
As the weather balloon rises through the stratosphere, the atmospheric pressure decreases. This lower pressure causes the gas inside the balloon to expand, leading to an increase in volume. The gas molecules have more space to spread out due to the reduced external pressure.
How fast is 343 ms?
343 m/s is the speed of sound through air at regular atmospheric pressure.
As soon as the intake valve opens what forces air through the carburetor and manifold to fill that vacuum?
Atmospheric pressure
Why do balloons expand as they rise through the troposphere?
The ballon contains a fixed amount of gas producing internal pressure. At the surface, this pressure equals the surface atmospheric pressure. As the balloon rises, the atmospheric pressure drops, allowing the balloon to expand, keeping the internal pressure and external pressure equal. If the balloon is fully inflated at the surface it will burst at higher altitude.
Which substances show sublimation at atmospheric pressure?
Common substances that exhibit sublimation at atmospheric pressure include carbon dioxide (dry ice) and iodine. These substances transition directly from solid to gas phase without passing through the liquid phase under normal atmospheric conditions.
How is a person able to drink using a straw?
Because he creates lower air pressure in his mouth compared to the atmospheric pressure - thus the liquid is pushed through the straw as a result of pressure difference.
