Why would a barometer show a greater reading when taken into a coal mine?
If the coal mine was deep (not a drift mine) it would register higher pressure due to the extra weight or air above it.

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 would sunshine look like like if there were no sun? If the barometer was any good it would read zero. Many barometers are not designed to handle that sort of extreme. Read More
Good question. Look at it like this if you had two barometers side by side, one a mercury barometer and the other a barometer that reacted to changes in air pressure using some bellows and a spring. Then, as the pressure changed you marked the second barometer positions and noted on the dial the inches reading from the mercury barometer, the second barometer measurement scale would mimic the real mercury barometer even though it did… Read More
Because it wouof go up and if u study enough u will no it right away Read More
A barometer does not measure temperature it measures pressure. Read More
It depends, a barometer can measure many different types of air pressure and there are different kinds of air pressure. your best bet would be to identify what type of barometer you have and simply read a dial. If you don't have a barometer and would just like to know what the maximum registered amount for high pressure is then you should consult you weather records centre. These following records i believe are the most… Read More
A barometer using water,would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference. This is because mercury is 13.6 times more dense than water. Read More
The barometer was rising so we thought it would be a good day for a picnic Read More
You would not get a true reading any longer. The forces of the electromagnet are greater than the natural magnetism of the Earth. Read More
No. The only thing that would matter is if the barometer were inside a pressure-sealed room. Read More
To analyze this problem you need to state between what two points the reading taken. Read More
Explain what a forensic entomologist would deduce from a short PMI taken using soil fauna but a long PMI taken using body fauna?
they would get soil reading from the short one, obviously, and body readings from the long one. Read More

a homeade barometer would probaby work the same way as a real barometer. It is made up of a long glass tube and a pool of liquid at the bottom. When the air pressure increases, the liquid would go to a higher level in the tube. when it decreases, the liquid wil sink in the tube. hope this helped! :) Read More
Evangelise Torricelli invented the mercury barometer in the 1600s. It was very accurate, but it was clumsy to move and had to stay upright. If humans hadn't invented the aneroid barometer, you would see big mercury barometers in all types of transportation. Read More

If a meteorologist says that the air pressure is getting lower what would you expect to see happen to Torricelli's mercury barometer?
If Torricelli had drilled a little hole at the top of the glass tube holding his mercury column, what would have happened to his barometer? Read More
The first number in an is the x - coordinate which is determined by the position on the and the second number is the y - coordinate which is taken from the?
the x coordinate is taken by reading across the x axis, which is the horizontal axis on a graph. The y coordinate is taken by reading up or down the y axis (vertical). For instance if x=5 and y=4 then we would normally write this as (5,4) or rectangular format. Read More

With a little modification yes. The principals of design for the Barometer and Altimeter are the same. A sealed capsule expands and contracts with changes in air pressure, this movement is then changed to the movement of a dial to get a scaled reading. However the Barometer would need its scale changing to read in terms of altitude. This would allow a rudimentary calculation of altitude, however as the air pressure changes, the altitude read… Read More
there must be vacuum in the mercury barometer because if air enters the tube the barmeter would become faulty as air pressure will change. Read More

Mercury (Hg) is preferred in a barometer because it is very dense (13.6 times that of water). Normal atmospheric pressure at sea level will support a column of Hg nearly 30 inches tall. But it will support a column of water about 30 feet high. That would be a big barometer... Read More

The height of a building can be easily measured with the use of a barometer. The process is as follows: -- With a barometer and a stopwatch, go to the roof of the building, and walk to the edge. -- Drop the barometer from the roof. Start the stopwatch when the barometer leaves your hand. -- Watch the barometer as it falls. Stop the clock as soon as the barometer hits the ground. -- Let… Read More
