decrease the temperature or increase the volume
In space, a helium-filled balloon will expand further due to the lack of air pressure outside the balloon. Eventually, the balloon will burst because the pressure from the helium inside will exceed the pressure outside.
The pressure that there would be if all the non-helium atoms and molecules were taken away.
Constricting the afferent arteriole would decrease blood flow into the glomerulus, leading to a decrease in pressure within the glomerulus. This may result in a decrease in glomerular filtration rate and a reduction in the formation of urine.
An increase in blood pressure, blood volume, or permeability of the filtration barrier would increase net filtration pressure. On the other hand, a decrease in blood pressure, blood volume, or an increase in plasma protein concentration would decrease net filtration pressure.
2.5 liters. The gas will fill whatever volume you put it in, no matter what (as long as it remains a gas and not a liquid). The only thing that will change is the pressure and/or temperature of the gas when making the transfer.
The pressure inside the container would decrease.
The pressure of the gas would also decrease.
In space, a helium-filled balloon will expand further due to the lack of air pressure outside the balloon. Eventually, the balloon will burst because the pressure from the helium inside will exceed the pressure outside.
Blood pressure would decrease
If the volume of the balloon doubles while the mass of helium remains the same, the density of helium inside the balloon would decrease by half. Density is calculated as mass divided by volume, so if volume doubles and mass stays the same, the density will decrease.
The pressure that there would be if all the non-helium atoms and molecules were taken away.
The pressure that there would be if all the non-helium atoms and molecules were taken away.
If a balloon were to decrease suddenly in size, the air pressure inside the balloon would increase, potentially causing it to burst. The sudden decrease in volume would also cause the gas molecules inside the balloon to collide more frequently with the balloon walls, exerting more force on them.
The heat can cause the air inside the balloon to expand, increasing the pressure beyond what the balloon can handle, leading to an explosion. Helium or not, any sealed container in extreme heat can experience this pressure buildup.
