Why in the terms of gas motion in the air does the pressure rise?

∙ 15y ago
Pressure increases if gas molecules slam into a surface either faster (higher temperature), hit harder (more mass), or more often (larger number of molecules). Pressure decreases if the gas molecules are generally moving parallel to the measuring surface, which is where the venturi effect and lift on wings can come from.

What effect does air density have on the absorption and radiation of energy?
An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
In the atmosphere a hot air layer is found above a cold air layer How is the separation achieved and why does hot air always tend to rise?
It is because a hot air is a light matter while a cold air is a heavy matter of gas. Like, the difference of low(hot) pressure and high(cold) pressure area.
Why do weather 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.
How does air cause a pressure against a car windscreen?
When a car is moving, this creates a difference in the relative velocity of the car as compared to the surrounding air. This creates a wind that presses on the windscreen. It doesn't actually matter, in terms of the amount of pressure, whether the car is not moving and the air is moving, or the car is moving and the air is not moving, what matters is only the difference in velocity between the car and the air.
Why doesnt air pressure crush objects?
There is air pressure on all sides, inside or outside. The air pressure pushes on the object all ways and nothing falls. If you only apply pressure on the bottom then the object will lift. If you apply pressure on the top, the object will collapse. If air pressure is pushing side ways, the object will move sideways.
What situations would cause air pressure to rise?
Air pressure begins to rise in a situation where there is a change in the temperature, especially when there is cold air hitting the ground. The rise in air pressure produces winds and different types of weather.
Air pressure is caused by?
air pressure is caused by the constant motion of air molecules
Draw a conclusion why is far weather common during periods of high pressure?
Sinking motion in high-pressure air masses makes it difficult for air to rise and clouds to form. That's why high pressure usually means good weather.
Why. Is fair weather common during periods of high pressure?
Areas of low pressure usually have cloudy weather. Sinking motion in high-pressure air masses makes it difficult for air to rise and clouds to form. That's why high pressure usually means good weather.
What happens to air pressure as you rise?
It decreases!!
Does the air in a low pressure region tend to sink or rise?
It tends to rise because it is warm air
The constant motion of air molecules cause?
air pressure
What happens to air pressure as you go up a mountain?
The air pressure slowly decreases as you rise in altitude.
How air pressure affects the motion of wind?
the air moves from areas of high pressure to areas of low pressure, this movement of the air is called "wind".
As you rise upwards in the atmosphere air pressure?
it decreases
As you rise further in the atmosphere air pressure does what?
The higher you go in the atmosphere the lower the air pressure becomes...
Which one of the following situations would cause air pressure to rise an increase in temperature cold air entering the region moisture entering the air?
Neither. The increase in altitude would cause air pressure to rise. :)
