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.
What type of weather is expected when air pressure rises?
When air pressure rises, it typically indicates the presence of high-pressure systems, which are associated with clear skies and stable weather conditions. As air descends in high-pressure areas, it warms and dries, leading to less cloud formation and lower chances of precipitation. Consequently, residents can expect sunny and calm weather when air pressure rises.
What a barometer with Mercury?
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
When pressure in the aorta rises due to atherosclerosis does more ventricular pressure open the aortic valve?
yes
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 pressure rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?
Intrapleural pressure rises and falls with breathing phases but eventually equalizes with atmospheric pressure. This pressure difference aids in lung expansion and ventilation by creating a pressure gradient for air to flow into and out of the lungs.
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
Does rain usually occur in high atmospheric pressure or low atmospheric pressure?
Rain typically occurs in low atmospheric pressure systems where air rises, cools, and condenses to form clouds and precipitation. High atmospheric pressure systems typically bring stable and clear weather conditions with less likelihood of rain.
When air pressure decreases the mercury in a barometer?
The mercury rises. The lower atmospheric pressure allows the mercury to drop in level.
What modern meteorological instrument measures atmospheric pressure?
A barometer is the modern meteorological instrument that is used to measure atmospheric pressure. It typically consists of a sealed glass tube filled with mercury that reacts to changes in pressure. The level of mercury in the tube rises and falls depending on the atmospheric pressure.
When intrapulmonary pressure increases over atmospheric pressure does air flows out of the lungs?
Yes, when intrapulmonary pressure increases above atmospheric pressure, air flows out of the lungs. This occurs during the process of expiration, where the diaphragm and intercostal muscles relax, decreasing the volume of the thoracic cavity. As the volume decreases, the pressure inside the lungs rises, causing air to be expelled until the pressures equalize.
What happens to the volume or size of a balloon as it rises in the air?
As a balloon rises in the air, the volume or size of the balloon increases. This is because the atmospheric pressure decreases as the balloon gains altitude, causing the air inside the balloon to expand and the balloon to inflate.
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 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.
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.
