Why is barometer useful?
Because it has a high density... meaning that the volume increase or decrease due to altitude change is can be viewed in a practical sized barometer. If water, which had a much lower density, was used instead of Mercury, the barometer must be at least 15m high.
Why does the seasons change according to mythology?
persephone, demeter's daughter is carried to the underworld every six months a year which causes the change of the seasons.
Does mass and weight change with altitude or elevation?
Mass does not change with changes in altitude or elevation. Weight on the other hand does change. However, on earth the change from sea level to the top of a mountain would be extremely small.
Will shadows on mercury change length more or less quickly than shadows on earth?
Less quickly becaus it takes longer to rotate on its axis therefore one mercury day equals 59 earth days
Would your mass change on an airplane mountain top or the beach?
No, weight changes but mass remains constant irrespective of the surroundings.
What is a mercury barometer?
A mercury barometer is a device that measures air pressure. The key component that distinguishes it from other barometers is the metal mercury.
Why must there be a near vacuum in the tube of mercury barometer?
there must be vacuum in the mercury barometer because if air enters the tube the barmeter would become faulty as air pressure will change.
How do fortin barometers work?
The way the Fortin barometer works is different in a sense that it uses atmospheric pressure to balance the weight of a column of mercury against it. From that, any change in the atmospheric pressure is accompanied by an immediate change in the level of the mercury and can be measured against the scale engraved on the barometer.
How would a barometer reading change with a cold front?
A barometer reading would change with a cold front because the density of mercury will change with temperature, so a reading must be adjusted for the temperature of the instrument. For this purpose a mercury thermometer is usually mounted on the instrument. Temperature compensation of an aneroid barometer is accomplished by including a bi-metal element in the mechanical linkages. Aneroid barometers sold for domestic use typically have no compensation.

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.
Why doesn't Mercury boil in the vacuum tube of a barometer?
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 indicates a change in weather?
A barometer.
What was the Mercury barometer used for?
The mercury barometer is a tool used by meteorologists and other scientists to find the air, or "barometric" pressure. Because mercury is liquid at room temperature, it can change shape due to changes in the atmosphere. Earth's barometric pressure is characterized as the downward force of air on the surface of Earth. If mercury is placed in a tube and the level decreases by a huge increment, it would show an increase in barometric pressure. Mercury barometers can also be used to detect incoming storms as right before a storm, the air pressure decreases drastically.
Why is mercury used in barometers instead of water?
Because it has a high density... meaning that the volume increase or decrease due to altitude change is can be viewed in a practical sized barometer. If water, which had a much lower density, was used instead of mercury, the barometer must be at least 15m high.
What does rapid changes in the barometer mean?
a barometer calculates changes in air pressure. so if it has a rapid change, im guessing it has just been a "rapid" change in air pressure
What weather tool can tell if the weather is about change?
a tool is a barometer
