How would the reading on a barometer change if you were to take one on a trip from Los Angeles to Lake Tahoe which is at a much higher altitude?

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
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.
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.
Which airplane instrument is really just a barometer?
An altimeter is sensitive to atmospheric pressure and can show the altitude of the aircraft based on the change in atmospheric pressure from the aircraft ascending and descending. Likewise, a barometer, is sensitive to atmospheric pressure.
Can a barometer be used as an altimeter?
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 on the scale would change. The Altimeter as used in aircraft also has a small thumb wheel or turntable knob that allows you to set the air pressure to the air pressure of the ground. This makes the scale more accurate, and negates any changes in air pressure.
What indicates a change in weather?
A barometer.
How does altitude affect phase change?
The change in pressure is highly affected by altitude.
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
How does air pressure change as altitude change?
Increased altitude means decreased air pressure.
What was used before the Barometer?
it tells us the change in the temprature.
What weather tool can tell if the weather is about change?
a tool is a barometer
What happens to air pressure's rate of change as altitude increases?
The rate of change of air pressure as a function of increasing altitude decreases with increasing altitude.
