Why must a barometer be place where are no temperature extremes?

The height of the Mercury column is used to measure atmospheric pressure. If the barometer is also subjected to high temperatures, the thermal expansion of the mercury column will indicate a higher pressure than is really the case. This will make the barometer readings useless.

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 instrument must you tap before reading the barometer on it?
do you have to tap a barometer daily to get correct reading
How a barometer can be used to measure the vapor pressure of a liquid?
A mercury thermometer, that is a barometer can be used to measure vapor pressure. Initially, a proper temperature must be recorded. Then the liquid should be injected into the mercury column. This new measurement subtracted from the original will yield the vapor pressure of a liquid.
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.
Why must a barometer be open to the air at one end and close at the other end?
A barometer is used for measuring atmospheric pressure. The barometer sealed on the top with an open bottom in order to allow air pressure to push down.
What is the average summer?
Average summer temperature varies from place to place around the world. You must state the place for which you want to know the average summer temperature, for example ask 'what is the average summer temperature in Montreal, Canada'.
Why must the I.S.S. have electrical power and insulation from temperature extremes?
The electrical circuits are affected by the magnetyic energy from space, so the circuits of the space station need to be iunsulated against magnetic energy.
Can an outlier be in the middle of a data set?
No, it cannot. It must be at one of the extremes.
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.
What must be true for metamorphism to occur?
the process must take place underground~ apex
Why must of barometer be open to the air at one end and close to the other?
becuase my peepaw said so
What is the pronoun for temperature?
The personal pronoun that takes the place of the noun 'temperature' is it.The pronoun 'it' can function as a subject pronoun or an object pronoun.example: The temperature is going up. It must be rising quickly. Please check it on the monitor.
