What fluids can be used to measure temperature?

Answer 1

The most common are mercury and alcohol. Mercury is being phased out because it is toxic. Alcohol thermometers are used to replace the old mercury thermometers.

Answer 2

Common fluids used to measure temperature include Mercury, alcohol, and thermochromic liquids. Mercury is toxic and less commonly used now, while alcohol-based fluids are safer alternatives. Thermochromic liquids change color with temperature variations, making them visually helpful for temperature readings.
