What else can I help you with?
If a container is half filled with a liquid and sealed at room temperature and atmospheric pressure then what happens inside the container?
Inside the container, the liquid would partially evaporate, creating vapor in the empty space above the liquid. Eventually, an equilibrium will be reached where the rate of evaporation equals the rate of condensation, resulting in a constant vapor-liquid mixture within the container.
Can vapor pressure occur in open container?
Yes, vapor pressure can occur in an open container. Vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase in a closed system. In an open container, vapor can still form above a liquid or solid substance, but it will not reach equilibrium as it can escape into the surrounding environment.
Can you siphon out of and back into the same container?
The basic principle of the syphon system is that the difference of pressure at both the ends of the tube would drive the liquid from the level of higher pressure to that of lower pressure. If, suppose, the level of liquid becomes the same in both the container then flow of liquid would stop. So, if you want to send back the liquid, then you have raise the container above the first one, then liquid would start flow from the second to the first.
What is the accurate definition of vapor pressure?
Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.
What is the gas pressure above a liquid at equilibrium called?
The gas pressure above a liquid at equilibrium is called the vapor pressure. This is the pressure at which the rate of evaporation equals the rate of condensation, leading to a dynamic equilibrium between the liquid and its vapor.
How does pressure due to a liquid held in a container vary with depth amount and shape and size of the container?
Pressure due to a liquid increases with depth because of the weight of the liquid above it. The pressure in a liquid is the same at a given depth regardless of the shape or size of the container, as long as the depth is the same. The shape and size of the container would only affect the pressure at different depths in the liquid.
What effect does the size of the container have on the pressure of the liquid at its bottom?
The horizontal dimensions of the container ... like length and width ... don't make any difference. But the pressure at the bottom is directly proportional to the depth of the liquid, which is ultimately limited by the height of the container.
If a container is half filled with a liquid and sealed at room temperature and atmospheric pressure then what happens inside the container?
Inside the container, the liquid would partially evaporate, creating vapor in the empty space above the liquid. Eventually, an equilibrium will be reached where the rate of evaporation equals the rate of condensation, resulting in a constant vapor-liquid mixture within the container.
What does not effect the pressure at a point beneath the surface of a liquid?
The shape of the container, the size of the container, and the density of the liquid do not affect the pressure at a point beneath the surface of a liquid. The pressure at a point in a liquid is only dependent on the depth of the point and the density of the liquid above it.
How does the pressure of a liquid depend on its depth?
consider an enclosed container with liquid filled to the brim, the pressure at any point in the container due to the liquid is given by this formula Pressure = height x density x acceleration due to gravity, and the height we are using here is not the height of this point above the ground, but instead it is the height difference (or simply length) between this point and the top of container, as we are measuring the pressure at this point due to the liquid above. similarly, you can consider a container that is not enclosed but you must remember to include the atmostpheric pressure into the total pressure at the particular point you are measuring. hope this helps =)
Why liquid pressure greatest in bottom?
Because above the bottom most layer there is maximum height of the liquid stands on. Also the expression for the pressure is hdg. h- height of the liquid. d-density of the liquid. g-acceleration due to gravity. Hence maximum h leads to max pressure.
Why do you think water from the different holes have different trajectories?
the trajectory of water is used as indicator of pressure. The longer the trajectory, the greater is the pressure at that point of the liquid column. Water pressure at any point in a closed container is dependent on the height of the liquid above it.
How to find gauge pressure in a closed container?
To find gauge pressure in a closed container, subtract the atmospheric pressure from the total pressure inside the container. Gauge pressure is the pressure above atmospheric pressure.
Vapor pressure is measured when a liquid and its vapor are?
in a state of dynamic equilibrium at a constant temperature. At this point, the rate of vaporization equals the rate of condensation, resulting in a constant pressure above the liquid known as the vapor pressure.
An increase in the temperature of a contained liquid?
An increase in temperature of a contained liquid will cause its molecules to move faster and further apart, leading to an expansion in volume. This expansion can potentially increase pressure inside the container if it is sealed, and may also change the physical state of the liquid (e.g. from solid to liquid, or liquid to gas) depending on the specific substance.
What will happen if a glass of bottle filled with a liquid sealed tightly and heated?
If heated to and above boiling point the pressure in the bottle would begin to rise. Depending on how much it is heated it might either stay like that, or the increased pressure might cause the bottle to burst.
Can vapor pressure occur in open container?
Yes, vapor pressure can occur in an open container. Vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase in a closed system. In an open container, vapor can still form above a liquid or solid substance, but it will not reach equilibrium as it can escape into the surrounding environment.
