Thermometer
The red liquid in a thermometre could either be alcohol, dyed red; or a substance called mercury, which is very toxic. Hope I helped :)
Yes, "thermometre" is the British English spelling of "thermometer."
To find the temperature
It's either mercury or colored alcohol. They're used because they expand in warmer temperatures, and contract in cooler temperatures, resulting in the rising and falling of the red line in your thermometer.

The Roman god is Mercury.
Mercury is a good option for use in thermometers because it has a high coefficient of expansion and contracts uniformly, making it easy to measure temperature accurately. It also has a wide range of temperature measurement (-39 to 356 degrees Celsius), making it suitable for various applications. Mercury is also a good conductor of heat, allowing for quick response times in measuring temperature changes.
