Detailed Solution

Gallium is used as a thermometric liquid because it has a relatively low melting point of 29.76°C (85.57°F) and a boiling point of 2204°C (3999°F), which allows it to be used as a liquid over a wide range of temperatures.

Additionally, gallium has a very low vapor pressure and does not react with many materials, making it a useful thermometric liquid in a variety of applications, such as in thermometers, thermostats, and heat transfer systems.
