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.

How would a barometer reading change if you went to a higher altitude?
Because it wouof go up and if u study enough u will no it right away
Why do they measure temperature in the shade?
Direct sunlight would heat the thermometer higher than the actual air temperature. A reading would be more accurate if taken in the shade, where the temperature reading would not be greatly different.
What would happen if you placed a compass near an electromagnet?
You would not get a true reading any longer. The forces of the electromagnet are greater than the natural magnetism of the Earth.
What instutment would you use to measure air preesure?
a barometer... and it is invented by torricelli..
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.
What would a barometer reading be if you there was no barometric pressure?
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.
How can an aneroid barometer give reading in inches of mercury when it doesn't use any mercury?
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 not actually use any mercury.
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.
When would the barometer be used?
The most commonly barometer used today would be a Aneroid.

Would it be hot or cold if a barometer was dropping?
A barometer does not measure temperature it measures pressure.

How do you put the word Barometer in a sentence?
The barometer was rising so we thought it would be a good day for a picnic
What is the highest air pressure a barometer can measure?
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 up to date: 1085.6 mb in Mongolia. The lowest recorded air pressure is 850 mbar in Manchester, South Dakota. In theory a barometer can record any amount of air pressure depending on its size. The larger the barometer, the greater range of measurement of air pressure. Currently the worlds largest Barometer resides in the Denmark Visitor Centre. You can find more about this Barometer at: http://www.bertbolle.com/
Why would a water barometer have to be 13.6 times taller than a mercury barometer?
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.
