A barometer measures atmospheric pressure, so if there was no barometric pressure, the barometer reading would likely show a value of zero or indicate an error. Atmospheric pressure is necessary for the functioning of a barometer.
a barometer looks like a clock but with words to know the air pressure.THANK YOU
The first barometer was a mercury barometer invented by Evangelista Torricelli in 1643. It consisted of a glass tube filled with mercury inverted in a dish of mercury. As atmospheric pressure changed, the mercury level in the tube would rise or fall, allowing for the measurement of air pressure.
a graduated cylinder looks like yo face
The opposite of barometer is likely to be an object that does not measure atmospheric pressure, like a clock or a thermometer.
during cold weather like rain storms or snow storms the barometer goes down. During warm weather the barometer goes up.
Air pressure is measured with a barometer.
Well, an aneroid barometer, is called an aneroid barometer- but, a barometer measures air pressure, and an aneroid barometer is a barometer that contains no liquid.
Dang it
barometer has mercury inside it .
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.
Yes, they are like thermometers and readily available for sale.
