Mercury stays contained in the tube of a mercury thermometer when in use. It does not escape into the air as long as the thermometer is intact. However, if the thermometer is broken or improperly disposed of, mercury vapor can be released into the air, which is harmful to health.
What else can I help you with?
Mercury stays in the test tube or escapes into the air?
Mercury stays in the test tube unless it is deliberately spilled or heated to a high temperature. The vapors from heated mercury can escape into the air, posing a risk of inhalation and toxicity. Proper handling and disposal are important to prevent mercury exposure.
Why the mercury can not rise in a lab thermometer if there is air in the glass tube?
Mercury does not rise in a lab thermometer if there is air in the glass tube because the presence of air creates pressure within the tube that opposes the expansion of the mercury. Without a vacuum, the air pressure prevents the mercury from moving freely up the tube in response to changes in temperature.
Where is the mass flow sensor located on a 2005 mercury montery?
On a 2005 Mercury Monterey : The Mass Air Flow Sensor would be between the engine air filter and the big engine air intake tube * on the Monterey I believe it is inside the engine air filter cover
Heated test tube using burner with closed air holes?
Heated test tube with a bunsen burner with closed air holes would result to the test tube having some kind of black material at the bottom, it looks like a burnt coal that stick to the bottom of the test tube. This happens because the flame is not a good flame.
What occupies the space above the mercury column in the barmoter's glass tube?
In a barometer, the space above the mercury column is typically a vacuum. This allows the mercury column to accurately reflect changes in atmospheric pressure without any interference from air molecules or other gases.
Mercury stays in the test tube or escapes into the air?
Mercury stays in the test tube unless it is deliberately spilled or heated to a high temperature. The vapors from heated mercury can escape into the air, posing a risk of inhalation and toxicity. Proper handling and disposal are important to prevent mercury exposure.
What pushes mercury up a tube in a mercury barometer?
the air off of Mercury has a big tube in the inside of it and it pushes in up
Why the mercury can not rise in a lab thermometer if there is air in the glass tube?
Mercury does not rise in a lab thermometer if there is air in the glass tube because the presence of air creates pressure within the tube that opposes the expansion of the mercury. Without a vacuum, the air pressure prevents the mercury from moving freely up the tube in response to changes in temperature.
What prevents mercury in the tube of a barometer from running out into the container at the bottom of the tube?
The top of a barometric tube is sealed leaving no place for air to escape. It works along the same principle as a drinking straw, but in reverse. In a drinking straw, the sucking motion reduces the pressure of the air inside the straw to a lower level than the air outside the straw. Liquid resists changes in volume due to pressure and is drawn up through the tube due to the air pressure exerted on the surface of the liquid outside the straw. In a barometric tube the tube is sealed at one end, trapping a finite amount of gas in the tube. The air pressure inside and outside the tube is equal, keeping the mercury suspended at a certain level. If the pressure outside is raised, more force is exerted on the surface of the mercury outside the tube than on the surface inside. This raises the level of the mercury in the tube until the pressure of the air is equalized -- there is still just as much air in the tube, but a smaller volume at a greater pressure.
Where is the mass air flow sensor on a 1998 mercury villager?
In a 1998 Mercury Villager, the mass air flow sensor is located in the air intake tube. The air intake tube goes from the air box to the intake.
What does a mercury barometer measure and how does it work?
A mercury barometer measures atmospheric pressure, which is the weight of the air pressing down on Earth's surface. It works by using a column of mercury in a sealed tube to balance the pressure of the air outside. When the air pressure increases, the mercury in the tube rises, and when the air pressure decreases, the mercury falls.
What is a mercury filled glass tube that measures air temperature called?
A mercury-filled glass tube that measures air temperature is called a mercury thermometer.
What happen to the level of mercury in the tude when the air pressuse decreases?
When the air pressure decreases, the level of mercury in the tube will rise. This is because the atmospheric pressure pushing down on the mercury in the dish will be less than the pressure from the column of mercury in the tube, causing the mercury to move up the tube until the pressures equalize.
Why must there be a near vacuum in the tube of mercury barometer?
A near vacuum is necessary in the tube of a mercury barometer to isolate the mercury from atmospheric pressure fluctuations. This allows the mercury to accurately reflect changes in pressure without external interference.
Why the mercury can not rise in a lab thermometer if there is air in glass tube?
Because the pressure of air may be greater than the pressure of the ascending Mercury.
What pushes Mercury up in a tube of a Mercury barometer?
That depends on the 'tube' involved. In a thermometer the mercury expands and contracts within a sealed tube as the temperature is raised or lowered. In a barometer there is a reservoir of mercury which the atmosphere presses on. This maintains the mercury in a column which is sealed at the top. Increases in atmospheric pressure push the mercury further up the tube, decreases let it drop down the tube.
What is mercury contained in a tube used to measure air temperature called?
thermometer
