SPM Physics Revision 2.2 Atmospheric Pressure 2.2.8 Anaroid Barometer

Anaroid Barometer

The anaroid barometer is usually used to measure altitude, which is named as altimeter.

Q & A

Q: Explain why the barometer can be used to measure altitude.

A:

The atmospheric pressure is inversely proportional to the altitude. The altitude can be determined from the atmospheric pressure.

Q & A

Q: Why a simple barometer is not suitable to be used to measure altitude?

Hard to be carried
Mercury is volatile. It can evaporate easily
Mercury is poisonous
