What is the liquid inside a thermometer?

In: Inventions, Physics, Chemistry [Edit categories]

Answer:

If it's silvery, it's probably mercury though if it's a newer thermometer it may be some low melting alloy such as Galinstan.

If it's red or blue, it's most likely alcohol with a small amount of coloring added to make it easier to see.
