What happens to the atmospheric pressure acting on the balloon as the balloon rises?
due to pressure inside the balloon, will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
When pressure in the aorta rises due to atherosclerosis does more ventricular pressure open the aortic valve?
yes
What a barometer with Mercury?
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
What happens to A V valves during ventricular contraction?
As the ventricles of the heart contract the pressure in the ventricles rises beyond that of the atria. This pressure differential causes the AV valves to shut.
What is the result when the pressure in the ventricles rises higher than the pressure in the atria?
Increased pressure in the ventricles means the heart has increased stress pumping blood to the respiratory system/ body.
What pressure rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapulmonary Pressure
What pressures rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapulmonary Pressure
What happens with altitude relative to pessure?
as altitude rises less there is less atmospheric pressure
When air pressure decreases the mercury in a barometer?
The mercury rises. The lower atmospheric pressure allows the mercury to drop in level.
Why does A balloon filled with hydrogen rises to a certain height then stops rising further?
the atmospheric pressure
What happens to the volume or size of a balloon as it rises in the air?
The volume of the balloon will increase as it rises in the air. This is because the atmospheric pressure decreases at higher altitudes.
What happens during atmospheric convections?
Warm air rises, and cool air sinks.
Why do a weather balloon keep increasing in volume as it rises through the stratosphere?
As it goes higher, the atmospheric pressure decreases.
What happens to the atmospheric pressure as one rises from sea level to the therosphere?
Rising from the sea level to the higher levels will result in decrease of temperature and 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.
Which property of the atmosphere does a barometer measure?
A barometer measures barometric pressure. Which is also known as Atmospheric Pressure. That's the pressure in the atmosphere that pushes down on you. When atmospheric pressure falls it can be a sign of potential t-storms and/or rain. Whereas when it rises it can be a sign of potentially fair weather.
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.
