there must be vacuum in the Mercury barometer because if air enters the tube the barmeter would become faulty as air pressure will change.
What else can I help you with?
Why vacuum is important on fresh water generator?
The purpose of the vacuum in the fresh water generator it can make a 50 degrees Celsius boil the water that's why they create a
What liquid is hardest to evaporate - petrolkerosenedieselroad tar?
Mercury, with a density 13 times more than that of water, it takes a long time to boil much less evaporate.
What are mercury barometers?
A barometer measures air pressure. A mercury one does so by taking a tube full of mercury which is inverted into a dish of mercury. The height of mercury remaining in the tube is a measure of the air pressure.
Do all liquids boil?
No. There are liquids that boil at a few degrees above absolute zero (helium for example) and liquids that boil at several thousand degrees above absolute zero (tungsten for example)
What is the boiling point of paper?
No, to boil, the material would have to be in a liquid state. Paper is not.
Why doesn't mercury boil in the vacuum of a barometer?
Becuase the presure just pushes it up and down so it couldn't boil because it would always be moving
Vacuum boiling water?
vacuum is measured in inches of mercury. sea level is zero. water will boil at 212F. as negative pressure or elevation increases the boiling temp. of water decreases. if you had a pressure reading of 29.7 in" of mercury the water will boil at 192F. if you had a pressure reading of 10 in" of mercury water will boil at 32F
As the pressure in a vessel containing water is reduced with a vacuum pump it begins to boil at some point but will it continue to boil if the vessel is sealed after it begins to boil?
If the vacuum pump is on, the water will continue to boil. If the vacuum pump is off as the vessel is sealed, the boiling will stop at a point of equilibrium.
What temp will gasoline boil under vacuum?
Gasoline will eventually boil under extreme vacuum at any temperature but the problem is trying to pull enough vacuum. During a recent experiment it took about 8 hours to pull enough vacuum to boil it to vacuum, the gasoline was at 72 degrees Fahrenheit. Temperature does play a small role when trying to boil under vacuum, this would be true if just trying to boil under normal atmospheric pressures. We pulled enough vacuum to double what was even in space not an efficient way to vaporize fuel.
Why does water boil in a vacuum?
Water boils in a vacuum because the surrounding pressure is reduced, allowing the water molecules to move more freely and escape the surface of the liquid as vapor. This lowers the boiling point of water, causing it to evaporate at a lower temperature.
Which metal you could boil in a Bunsen flame?
lead
Does water boil in a vacuum?
YesThis is because boiling is caused by the liquid water turning to gas which is not influenced directly by other materials. However, once in a vacuum the pressure is so low that the water will boil at much lower temperatures.
How can you boil water at a temperature lower than 100 celsiuse?
Place the container of water in a vacuum & it should start to boil at room temperature.
When alchohol and mercury boil they both change from a liquid to what?
They change from a liquid to a vapor (gas).
What is the boiling of water in degrees celsius?
The amount of heat needed to boil water varies with the air pressure. Water in a vacuum will boil at room temperature.
How do choose a vacuum pump Make water at Boil 1 degree C Thank you?
Choose a vacuum pump with a 29.75 hg that makes water boil 1 degree C. The typical boiling point of water is hundred degrees Celsius.
What energy is used to make water boil?
this web page doesnt work that well
