What element is used in a barometer?
Barometers can use any liquid. A dense liquid that makes for a short column at room temperature, is mercury.
Why are aneroid barometers often more practical than mercury barometers?
The aneroid barometer is more durable and compact, and much easier to read. The only particular advantage of a mercury barometer is that it's a direct measurement -- there's no calibration involved. If you can measure the height of the column above the pool and you know the density of mercury, you have the pressure.
What does a fluorescent light tube usaually contain?

Why are fluorescent lamps classified as hazardous waste?
Fluorescent lamps or light bulbs contain various amounts of mercury in them. When they are thrown away they are eventually broken and the mercury can leak out. That makes them hazardous to people, animals, and the environment.
