Function ofbulb of sphygmomanometer?
The function of the bulb of a manual sphygmomanometer is to inflate the cuff to stop the flow of arterial blood in the arm so that the blood pressure can be determined. The bulb pumps air into the cuff, causing it to expand against the upper arm. Enough air is pumped into the cuff to stop the flow of arterial blood. The pressure is then slowly released and the point at which blood begins to flow again is recorded as the systolic pressure, representing the highest arterial pressure of the cardiac cycle. Blood flows only with the beating of the heart, however, and further pressure is released until the arterial blood flows freely. This point is recorded as the diastolic pressure, representing the lowest arterial pressure when the heart is at rest.
Expand means to get what?
Expand generally means to expand the problem. I'm assuming this is a function, you'd expand it into a simpler form (factor things out and such).
What happens to the volume and pressure of the gas in the cylinder?
When a gas in a cylinder is compressed, the volume decreases while the pressure increases, according to Boyle's Law, which states that pressure and volume are inversely related at constant temperature. Conversely, if the gas is allowed to expand, the volume increases and the pressure decreases. Changes in temperature can also affect pressure and volume, as described by the ideal gas law (PV=nRT). Overall, the relationship between volume and pressure is fundamental to understanding gas behavior in a closed system.
How does a cartesian diver work?
A Cartesian diver operates on the principles of buoyancy and pressure. It consists of a sealed, partially filled container (the diver) that is buoyant in water. When pressure is applied to the outside of the container, the air inside the diver is compressed, increasing its density and causing it to sink. Releasing the pressure allows the air to expand, decreasing the diver's density, which then causes it to float back to the surface.
Why does the air behave in this way in cartesian diver?
In a Cartesian diver, the air behaves as it does due to the principles of buoyancy and pressure. When the container is squeezed, the water pressure increases, compressing the air inside the diver. This increased pressure reduces the volume of air, making the diver denser than the surrounding water, causing it to sink. Releasing the pressure allows the air to expand, decreasing the diver's density, and making it buoyant again, allowing it to rise.
What would cause a balloon to expand if taken to the top of a mountain?
Lowered Pressure
What happens as you push up the balloon?
As you push up a balloon, the air inside it is compressed, causing the pressure to increase. This can lead to a decrease in the volume of the balloon if it is not elastic enough to expand. Additionally, if the balloon is pushed into a region with lower pressure, it may expand as the external pressure decreases. Ultimately, the balloon's behavior depends on the balance between the internal air pressure and the external environmental pressure.
How does the altitude effect the size of a balloon?
As the external pressure drops with increasing altitude, balloons generally expand with height.
Why does external pressure greatly affects the size of the lungs?
External pressure significantly affects lung size because the lungs operate based on the principles of pressure and volume, as described by Boyle's Law. When external pressure increases, such as during deep-sea diving or high-altitude environments, it compresses the air within the lungs, reducing their volume and making it harder to expand. Conversely, lower external pressure allows the lungs to expand more easily, increasing their volume. This dynamic is crucial for efficient gas exchange and overall respiratory function.
What is the gas law about sealed bag of chips expand when in higher altitude?
The ideal gas law states that as altitude increases, air pressure decreases. This lower pressure causes the bag of chips to expand because there is less external pressure pushing on the bag. The gases inside the bag expand to fill the increased volume.
If you put a plastic ball in a container what will happen?
The plastic ball will remain in the container unless moved or acted upon by an external force. It will not change its state unless there is an external influence such as another object pressing against it or a change in temperature or pressure causing it to expand or contract.
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.
Why does a tire expand as you pump air into it?
because you're putting pressure inside the tire of the required psi recommended
When air pressure decreases size of the airtight container blank?
When air pressure decreases, the size of the airtight container may expand if it is made of a flexible material. This occurs because the higher pressure inside the container pushes outward against the lower external pressure. However, if the container is rigid, it will maintain its size, but the contents inside may experience a change in pressure that can affect their state or behavior.
What causes excessive coolant loss?
Normally a leak in the sytem, either internal or external. More details would be required to expand on the answers to be given
What would happen if you put a balloon in the sun?
It would expand as the gases inside expand against the pressure of the skin of the balloon and the atmospheric pressure.
Why does a balloon get bigger as you go up in elevation?
A balloon gets bigger as you go up in elevation because the atmospheric pressure decreases with altitude. At higher elevations, the external pressure on the balloon is lower, allowing the gas inside to expand. This expansion occurs until the internal pressure balances with the external pressure, causing the balloon to increase in size.
