What would the pressure be in a liquid contained in a vertical tube sealed at the top with a submerged open bottom be?
It would be the same as the pressure in the liquid outside the tube at the open end- the deeper it is in the liquid, the higher the pressure.
If a smell - diameter open glass tube is partially immersed in a vessel containing mercury the surface of the mercury inside the tube will be?
convex
What type of barometer was invented first the aneroid or the mercury?
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
My door open sensor on the dashboard says you have a door open....but they are closed ...2000 mercury villager...fix how?
Have you checked the rear hatch glass ?? Open it and reclose it firmly.
Does the glass tube in a fire sprinkler expand more or less than the liquid inside the tube How do you know?
Loads more The liquid expands more than the glass envelope. You know this because the mechanism is designed to open the water valve to the sprinkler head when the glass envelope shatters when the liquid ruptures it as it heats up.
What is capillary tubes?
In chemistry... it's a thin open-ended glass tube for collecting small amounts of liquid. Inserting one end of the tube into liquid allows the liquid to flow upqwards. When the liquid reaches a suitable height, a finger placed over the open end (towards the top) holds the liquid in the tube - for transferring from one place to another.

What is the method of memorizing which plants are floating or partially submerged or totally submerged?
Yes,just open book read it 50 times you will remember all.
How can you prove that atmosphere exerts pressure?
The original experiment that demonstrated this was a portable Mercury column.If you have a large bowl full of Mercury (a liquid metal) and a 1 meter long glass tube open at one end, then you can make a simple barometer. First, completely fill the tube with mercury, and temporarily close of the open end of the glass tube with a fitted seal, so the glass tube will be completely full of mercury and closed at both ends. Then stand the inverted tube (with its sealed end in the bowl of mercury), and while the end of the tube is immersed in the mercury, remove the fitted seal, allowing the mercury trapped inside the tube to flow into the bowl. Some of the mercury will flow out of the tube into the bowl, but the air pressure will cause the remaining mercury remain in the tube up to a height of (about) 760 mm above the mercury level in the bowl. The volume in the tube above the column of mercury will be filled with a vacuum..If you were to then take your portable barometer on a hike up a mountain, you would notice that the volume of the vacuum in the tube would become greater, and the column of mercury in the tube become shorter. This is because the atmospheric pressure keeping the mercury up the tube is lower at a higher altitude..Note: Mercury is a dangerous substance and must be handled with care. The above experiment should not be attempted except under the supervision of qualified laboratory personnel..See the related link below.
Which chemical could turn mercury to solid form and never turn liquid form even after giving high temperature?
Hot sulphuric acid in open air turns the Mercury into Mercuric sulphate which is a high melting solid.
Why the surface of the mercury in a glass tube is con vex end that of water concave?
Mercury has a low adhesive force to glass, it would rather bond to itself than another surface. This tends to create a spherical surface on open mercuric faces. Balanced by gravity the hemisphere flattens and creates the slight convex shape observed.
Didn't the original etch a sketch have mercury in it?
No. The Etch-A-Sketch has always contained aluminum powder and plastic beads. Mercury would not work, as it would clean the glass, rather than coating it.
