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?
Vapor pressure
How can the boiling point of a liquid be raised without adding soluble impurity?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, or the pressure above the liquid. So, to increase the boiling point without adding a solute, one can increase the pressure above the liquid.
What are the signs that a liquid has reached its boiling point?
Oh come one -_-''Its obviousBubbles of vaporised liquid will formThe temperature of the liquid when boiling will remain constant even when more heat is applied.As the liquid is heated, the vapour pressure increases until it equals the pressure of the gas 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 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.
Why atmospheric pressure varies with height in a different way from the way liquid pressure varies with depth.?
For the same reason. The liquid above the location considered, or the atmosphere above the position considered, helps contribute to the pressure; if there is more liquid or atmosphere above, there is more pressure.
What is the gas pressure above a liquid at equilibrium called?
Vapor pressure

What happens at a liquid's boiling point?
Boiling. A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it.
At what pressure gas will be convert into liquid?
Above Critical Pressure. This will depend on the gas and its temperature.
Why is there a mist over the neck of the bottle when you open a chilled bottle of lemonade?
Any liquid left in a container will evaporate. When placed in a closed container, there will be an equilibrium between the liquid and its vapour present above the liquid. When the bottle is chilled, the falling temperature causes the vapour present above the liquid to condense to form liquid again which appears as mist on the inside of bottle.
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.
Is aliminuim a liquid?
Above 660.3 oC, aluminium is a liquid. Presuming normal atmospheric pressure.
