An aneroid barometer is different from a mercury barometer in that it?
An aneroid barometer, invented by the French 19th century engineer and inventor Lucien Vidie, uses a small, flexible metal box called an aneroid cell. This aneroid capsule (cell) is made from an alloy of beryllium and copper. The evacuated capsule (or usually more capsules) is prevented from collapsing by a strong spring. Small changes in external air pressure cause the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer.A mercury barometer has a glass tube of at least 84 cm in height, closed at one end, with an open mercury-filled reservoir at the base. The weight of the mercury creates a vacuum in the top of the tube. Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. High atmospheric pressure places more force on the reservoir, forcing mercury higher in the column. Low pressure allows the mercury to drop to a lower level in the column by lowering the force placed on the reservoir. Since higher temperature at the instrument will reduce the density of the mercury, the scale for reading the height of the mercury is adjusted to compensate for this effect.
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
Is Mercury bad for you?
Highly. Mercury is one of the most poisonous substances on Earth. Depending on how you're exposed to it, it can cause irreversible damage to vital organs and eventually death.
What is an example of thermal expansion that you have observed in your daily life?
an example would be a thermometer. A thermometer because it has mercury in it. When you check a patients temperature with a thermometer ,the heat from the patients body will cause the expansion of the mercury and the mercury flows in the tube. It stops at a point and that point indicates the temperature in the patients body.
Why can flashlights be nonluminous?
there are three reasons that cause the flashlight non 1. battery is out of power 2. the tmeperature of bulb is too height to cause short circuit 3. soaking
As air pressure increases does the height of a column of mercury in a barometer increase?
Yes, as air pressure increases, the height of the column of mercury in a barometer also increases. This is because the higher air pressure pushes down on the mercury in the barometer, causing the column to rise. Conversely, lower air pressure will cause the column of mercury to fall.
What does a decrease in the height of the mercury column usually indicate on a barometer?
low pressure system and stormy weather
What would cause smoking wires in the steering column in a 1993 mercury tracer?
Overload or short to ground

What can cause 1993 Buick LeSabre steering column smoke?
only thing that will cause smoke in steering column,is an electrical short in the wiring inside the steering column
What are the difference between the mercury barometer and aneroid barometer?
A mercury barometer works by, measuring the height of a column of mercury in a sealed tube, supported by the atmospheric pressure.An aneroid barometer measures the amount of distortion of a sealed metal can, due to changes in atmospheric pressure. The equivalent column of mercury supported by a mercury barometer, can then be calibrated in mmHg by comparison.Both instruments do the same job and can be calibrated in Millibars or mmHg, or both.
Would a mercury manometer be able to measure a smaller pressure increment then a water manometer?
cause of the about of nice bits floating around Mercury is better because 1) it doesn't evaporate 2) water has a density 13.6 times lower than mercury, so for some applications the size of the manometer would have to be very large.
On a Mercury Mystique what would cause the center brake light to work but not the the rear two brake lights?
problem is in the steering column wires, jiggle and check. remove steering column, and sit in drivers seat. with left hand reach right next to dash and sterring column there will be a wire harness(BLACK) top left jiggle that one..
Why the Mercury-in-glass thermometer first descends and then rise when put in flame?
When placed in a flame, the glass bulb expands rapidly. This increases the volume of the bulb and so the column descends. However, the glass then conducts the heat to the mercury so that it undergoes thermal expansion and the column rises.
What are causes of paralysis?
One main cause of paralysis is a major accident such as a car crash, a fall from a high height or any other hard impact to the spinal column. Other causes are hereditary.
What are the dangers of using mercury?
Mercury is highly toxic and working with it can cause mercury poisoning.
